A S-bridged Co~(III)Au~ICo~(III) Trinuclear Co~(III)plex with L-Cysteinate Acting as a Flexible Dicarboxylate-type Metalloligand toward Manganese(II)

摘要

Treatment of a S-bridged Co~(III)Au~ICo~(III) trinuclear complex [1]~(3+), newly prepared from Δ_L-[Co(L-cys-N,S)(en)2]~+ and Au~I, with MnCl2 gave a 1D (Co~(III)2Mn~(II)Au~I)_n polymeric complex, in which two carboxylate groups of [1]~(3+) bind to two MnCl2 moieties. On the other hand, a discrete Co~(III)2Mn~(II)Au~I tetranuclear complex, in which two carboxylate groups of [1]~(3+) chelate to a Mn(NO3)2 moiety, was produced by similar treatment of [1]~(3+) with Mn(NO3)2.
