Control of 1D Wave versus 2D Honeycomb (CoCdCuI)-Cd-III-Cu-II Heterotrimetallic Architectures by Delta(L)-Lambda(L) Diastereoisomerism of L-Cysteinatocobalt(III) Building Units
The reactions of the Delta(L) and Lambda(L) isomers of [CO(L-Hcys-NS)(en)(2)](2+) (L-H(2)cys = L-cysteine) with CuCl in aqueous HCl gave (CoCuI)-Cu-III dinuclear complexes with the same S-bridged structures, Delta(L)-1 and Lambda(L)-1. When Delta(L)-1 was treated with CdCl2 in water, a 1 D wavelike ((Co2CdCuI)-Cd-III-Cu-II), polymeric complex (2) was produced. On the other hand, similar treatment of Lambda(L)-1 led to the formation of a 2D honeycomb-like ((Co3Cd3CuI)-Cd-III-Cu-II)(n) polymeric complex (3), supported by the presence of counter-monoanions.
