1 Introduction Heterobimetallic paddlewheel (PW) complexes [MTr(SOCR)4L] (M = Pt, Pd; Tr = first-row transition metal; L = Tr-coordinated axial ligand) display a remarkable variety of supramolecular arrangements in the solid state, with dimeric structures supported by M···M' and M···S' contacts as the most common motif (dots indicate intermolecular contacts) [1]. Over the years, the group of L. Doerrer has introduced and refined a useful and widely adopted classification of these dimers [1, 2].

The structure of a pentachromium(II) extended metal atom chain at 3 K: Cotton’s conjecture proven Andrea Cornia, Alessio Nicolini, Charles J. McMonagle and Michael Probert Abstract We provide definitive experimental proof that the archetypal string-like compound [Cr5(tpda)4(NCS)2] has alternating long and short Cr-Cr separations in the solid state, as conjectured by F. A.

Abstract A chiral tetragallium(III) complex isostructural with the family of propeller-like FeIII3MIII single-molecule magnets (M=Fe, Cr, V) was prepared and found to give spectacularly resolved 1H NMR spectra in solution. We clearly identified two diastereoisomers with different symmetry in solution and used density functional theory calculations to demonstrate that their Λ and Δ optical antipodes interconvert slowly over NMR timescale.
