Abstract

Four new three-dimensional heterometallic coordination polymers (CPs), {Zn-3(Hen)(OH)}{Cu-6(6-mna)(6)}<bold></bold>(H2O)(6)] (I), {Zn-2(OH)(en)}{Cu-6(6-mna)(6)}(0.5)<bold></bold>(H2O)(2)<bold>EtO H</bold>] (II), {Zn-3(dap)(3)(H2O)}{Cu-6(6-mna)(6)}<bold></bold>(H2O)(4)] (III), and {Zn-2(4,4-bpy)(0.5)(OH)(H2O)}{Cu-6(6-mna)(6)}(0.5)<bold></bold>(H 2O)] (IV) (en = ethylenediamine, 6-H(2)mna = 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 Cu-I- and Zn-II-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.
