摘要：

A remarkable self-assembly system based on the chiral Co IIIHgIICoIII trinuclear complex with two pendent L-cysteinato carboxyl groups was investigated. Compound δLδL-1 was isolated as dark-red needle crystals from the 2:1 reaction of δL-[Co(L-Heys)(en) 2] (ClO4)2 and Hg(ClO4)2 in aqueous HClO4. The IR spectrum of δLδ L-1 is an expected S-bridged CoIIIHgIICo III trinuclear complex with two pendent COOH groups. The other COO- group of each CoIIIHgIICoIII has an axial orientation and is hydrogen bonded with two enamine groups of the mononuclear unit. The results suggest valuable insight into the design and creation of self-assembly systems that reversibly afford functional metallosupramolecular species in response to external factors.
