Stimuli-responsive Pd2L4 metallosupramolecular cages: towards targeted cisplatin drug delivery
Stimuli-responsive Pd2L4 metallosupramolecular cages: towards targeted cisplatin drug delivery† Metallosupramolecular cages are an emerging, but as of yet relativity unexplored, drug delivery vector. Herein we show that discrete dipalladium(II) molecular cages of the formula [Pd2L4](X)4 can be quantatively self-assembled from a simple tripyridyl ligand (2,6-bis(pyridin-3-ylethynyl)pyridine) and [Pd(CH3CN)4](X)2 (X = BF4− or SbF6−).
Slow magnetic relaxation in Dy2 and Dy4 complexes of a versatile, trifunctional polydentate N,O-ligand
Slow magnetic relaxation in Dy2 and Dy4 complexes of a versatile, trifunctional polydentate N,O-ligand A tridentate ligand LH3 (C11H13N3O4) comprising o-vanillin, hydrazone and oxime donor groups has been employed to prepare a new class of di- and tetranuclear LnIII complexes.
A New Nitrogen Rich Open Chain Diazine Ligand System: Synthesis Coordination Chemistry and Magneto-Structural Studies
The synthesis and coordination chemistry of a new series of open chain diazine base ligands (L3aH2, L3bH2, and L3cH2 ) is reported. The ligands comprise a central disubstituted bipyridine moiety with two bridging alkoxide oxygen donors, together with diazine and pyridine terminal groups strategically located to coordinate three metal centres. Reactions of L3aH2 and L3bH2 with CuX2 (X- = ClO4, Cl, NO3) yield a trinuclear complex (1) and 1-D copper chains (2 , 3).
A new nitrogen rich open chain diazine ligand system: synthesis coordination chemistry and magneto-structural studies
The synthesis and coordination chemistry of a new series of open chain diazine based ligands (L H , L H , and L H ) is reported. The ligands comprise a central disubstituted bipyridine moiety with two bridging alkoxide oxygen donors, together with diazine and pyridine terminal groups strategically located to coordinate three metal centres. Reactions of L H and L H with CuX (X = ClO , Cl, NO ) yield a trinuclear complex (1) and 1-D copper chains (2, 3).
Synthesis, characterization and magnetic studies on mono-, di-, and tri-nuclear Cu(II) complexes of a new versatile diazine ligand
The synthesis and coordination chemistry of a new open-chain diazine ligand (L4H2) containing bipyridine, oxime and hydrazone functionalities is reported. Reaction of L4H2 with CuCl2·2H2O affords the mononuclear complex Cu(L4H2)Cl2 (1) in which the ligand acts as a neutral tridentate N,N?,N? donor, whereas treatment with a large excess of CuCl2·2H2O affords the dinuclear complex Cu2(L4H)Cl3(CH3OH)(H2O) (2) in which the ligand is singly-deprotonated at the diazine, offering N,N?,N? and N,N?
Encapsulation of a [Dy(OH2)8]3+ cation: magneto-optical and theoretical studies of an emissive SMM displaying slow relaxation via the second excited state - Chemical Communications (RSC Publishing)
The first supramolecular cage formed by three benzo-15-crown-5 macrocycles encapsulating a [Dy(OH2)¬8]3+ guest cation is reported, with the Dy(III) centre exhibiting local square antiprismatic D4d symmetry.
