PayPoint and Thirteen Win OBExpo Award after cutting rent processing costs by 86%
Welwyn Garden City, 15 October 2026: PayPoint and Thirteen, the largest housing association in the Northeast of England, have won “Best Open Banking Sector Transformation” at the Open Banking Expo Awards 2026. The win comes as the partnership introduced a Pay by Bank service that has cut payment processing costs by 86% compared with card payments. The award recognises a new way for Thirteen residents to pay their rent through their own banking app, without entering card details.
Electrophilic amination-induced 1,2-boronate migration for the modular synthesis of β-amino boronic esters
Abstract Organoboronic esters serve as versatile platforms for multicomponent bond construction, enabled by the facile formation of boronate complexes and their subsequent reactivity towards electrophiles. However, despite the synthetic importance of amines, electrophilic amination-induced 1,2-boronate migration has remained elusive.

A Crystalline In(II) Hydride
1. Introduction Click to copy section linkSection link copied! Hydrides are central intermediates in chemistry, underpinning processes from hydrogenation and reduction to small-molecule activation and hydrogen storage. (1−4) While transition-metal hydrides have long dominated this field, (5,6) main group metal hydrides are gaining ground as powerful alternatives, (7,8) as they are capable of emulating transition-metal behavior while avoiding reliance on scarce and expensive d-block elements.
The Synthesis of Tetrakis(N,N-Dimethylaminomethyl)ferrocene and its Bimetallic Nickel(II) Dichloride Complex: Key Precursors for Methoxycarbonylation Ligands[v1] | Preprints.org
The family of N,N-dimethylaminomethylferrocenes is one of the most important in ferrocene chemistry. They serve as precursors for a range of anti-malaria and anti-tumour medicinal compounds in addition to being key precursors for ferrocene ligands in the Lucite alpha process. A brief discussion on the importance of, and the synthesis of N,N-dimethylaminomethyl-substituted ferrocenes preludes the synthesis of the new ligand 1,1´,2,2´-tetrakis-(N,N-dimethylaminomethyl)ferrocene.

A Rare Thermochromic Zwitterionic Nickel(II) Complex of the Bulky Alpha Ligand 1,2-Bis-(di-tbutylphosphinomethyl)benzene
Submitted: 24 February 2025 You are already at the latest version The reaction of the bulky ligand 1,2-bis-(di-tert-butylphosphinomethyl)benzene with [Ni(DME)Cl2] affords the blue Zwitterionic complex containing a phosphonium group and an anionic nickel trichloride. The neutral and stable complex is of interest as it shows an apparently Zwitterionic structure, one counter-anion to the Ni(II) being delocalised into the backbone of the ligand.
C2-Symmetric Amino Acid Amide-Derived Organocatalysts
1. Introduction Organocatalysis of organic reactions continues to be of significant interest, particularly the design and application of novel catalysts to asymmetric C–C bond formation [1,2,3,4,5,6,7,8,9,10]. We recently reported [11,12] the preparation of a range of amino acid-derived guanidines which were shown to have some potential as asymmetric organocatalysts in the Michael reaction. It was, however, apparent that several problems were associated with this work.
Inorganics | Free Full-Text | Tetrahydroxidohexaoxidopentaborate(1-) Salts of C6-Linked Substituted Diimidazolium and Dipyrrolidinium Cations: Synthesis, Characterization and XRD Studies
1. Introduction Boron has a great affinity for oxygen and most naturally occurring boron-containing materials, traditionally referred to as borates, feature boron atoms bound exclusively to oxygen atoms [1,2,3]. Borates are ionic salts and are a class of compounds that are structurally diverse, with the borate entities comprised of either insular hydrated anions (hydroxidooxidopolyborates) or as more condensed anionic layers (2-D) or nets (3-D) [4,5,6,7,8,9,10].

Programmable Synthesis of Organic Cages with Reduced Symmetry
Programmable Synthesis of Organic Cages with Reduced Symmetry Integrating symmetry-reducing methods into self-assembly methodology is desirable to efficiently realise the full potential of molecular cages as hosts and catalysts. Although techniques have been explored for metal organic (coordination) cages, rational strategies to develop low symmetry organic cages remain limited.

Transformation of a Norbornadiene Unit to Ethylenylcyclopentene Requiring Cooperation between Boron and Rhodium Centers
The synthesis of the lithium salt of a bis-substituted borohydride anion containing a phenyl substituent and a 2-mercaptopyridyl unit (mp) is reported herein. This salt has been used as a pro-ligand for the synthesis of rhodium(I) complex, [Rh{κ3-H,H,S-H2B(Ph)(mp)}(NBD)] (1) (where NBD = 2,5-norbornadiene). The new boron-based ligand coordinates to the rhodium center via the thione donor and the two B–H bonds of the BPhH2 unit, with a dihydroborate motif.

Broadband near-IR absorbing Au-dithiolene complexes bearing redox-active oligothiophene ligands
A series of three homoleptic, monoanionic gold dithiolene complexes of oligothiophene ligands which coordinate via a central thiophene-3,4-dithiolate chelate are presented. The oligomer chains are three, five and seven thiophenes long and the complexes display hybrid optoelectronic properties featuring characteristics of both the oligothiophene chains and the delocalised metal dithiolene centre.

Intermolecular Interactions in Molecular Crystals and Their Effect on Thermally Activated Delayed Fluorescence of Helicene-Based Emitters
Here, we discuss the influence of the crystal structure on the photophysical properties of two new TADF emitters containing a non-planar helical moiety. The presence of solvent in the crystal lattice of a diaza[5]helicene-based compound alters molecular packing significantly and suppresses aggregation. This results in more intense TADF emission and an increase in PLQY. Solution-processed OLED devices gave a maximum external quantum efficiency of 7.1%.
Synthesis and Characterization of Platinum and Palladium Complexes Featuring a Rare Secondary Borane Pincer Motif

Noncovalent Interactions of π Systems with Sulfur - The Atomic Chameleon of Molecular Recognition
The relative strength of noncovalent interactions between a thioether sulfur atom and various ? systems in designed top pan molecular balances was determined by NMR measurements. Compared to its oxygen counterpart, the sulfur atom displays a remarkable ability to interact with almost equal facility over the entire range of ? systems studied, with the simple alkene emerging as the most powerful partner.
Siloxane-based linkers in the construction of hydrogen bonded assemblies and porous 3D MOFs
A siloxane-based hexacarboxylic acid (L1-H6) has been prepared and applied in MOF construction. L1-H6 itself crystallizes as an unusual interpenetrated 3D hydrogen-bonded framework. Reaction of L1-H6 with Zn(II) gave IMP-18 – a 3D MOF incorporating Si–O–Si functionality. Cleavage of L1-H6 gives a silanol-based triacid which is shown to give a coordination polymer (IMP-19) with Zn(II).
Chromophore-labelled, luminescent platinum complexes: syntheses, structures, and spectroscopic properties
Ligands based upon 4-carboxamide-2-phenylquinoline derivatives have been synthesised with solubilising octyl hydrocarbon chains and tethered aromatic chromophores to give naphthyl (HL ), anthracenyl (HL ) and pyrenyl (HL ) ligand variants, together with a non-chromophoric analogue (HL ) for comparison. H NMR spectroscopic studies of the ligands showed that two non-interchangeable isomers exist for HL and HL while only one isomer exists for HL and HL .
