- Abstract
Four new three-dimensional heterometallic coordination polymers (CPs), [{Zn3(Hen)(OH)}{Cu6(6-mna)6}·(H2O)6] (I), [{Zn2(OH)(en)}{Cu6(6-mna)6}0.5·(H2O)2·EtOH] (II), [{Zn3(dap)3- (H2O)}{Cu6(6-mna)6}·(H2O)4] (III), and [{Zn2(4,4'-bpy)0.5(OH)- (H2O)}{Cu6(6-mna)6}0.5·(H2O)] (IV) (en = ethylenediamine, 6- H2mna = 6-mercaptonicotinic acid, dap = 1,2-diaminopropane, 4,4'-bpy = 4,4'-bipyridine), have been synthesized and their structures determined by single-crystal X-ray crystallography. The compounds consist of Cu6S6 octahedral clusters linked through the carboxylates to different zinc-oxo clusters. Thus, the compounds contain CuI- and ZnII-based clusters, which are not commonly observed in coordination polymer structures. Compound I stabilizes in a NiAs-related structure, compounds II and IV in a NaCl-related structure, and compound III is a new type of network structure. All the compounds were active catalysts in the heterogeneous nitroaldol reaction.
