Two isomorphous transition metal complexes displaying a coordinated tetrathionate unit: Bis(4,4′-dimethyl-2,2′-bipyridine- κ2 N,N′)(tetrathionato-κ2 S,S′)cadmium(II) dimethylformamide disolvate and the zinc(II) analogue

Mostrar todas las versiones(3)

The isomorphous title compounds, [Tr(S4O6)(C 12H12N2)2]·2C 3H7NO (Tr = CdII and ZnII), consist of metal centres to which one tetrathionate and two 4,4′-dimethyl-2, 2′-bipyridine chelating ligands bind. The structures are completed by two symmetry-related dimethylformamide solvent molecules. Each met...
