A Cobalt-Zinc heterometallic coordination polymer

The connection of metal–organic coordination polymers based on transition metals and multifunctional bridging ligands has proven to be a promising field due to their intriguing topologies and potential functions in material chemistry [1,2]. Over the past decade, different classes of coordination polymers have been success fully designed and synthesized. Recently, bridging ligands containing N- or/and O-donor s, for example, polycarboxylate aromatic anions including benzene-1, 2-dicarboxylate, benzene-1,3-di carboxylate, benzene-1, 4-dicarboxylate, benzene-1,2,3-tri carboxylate, benzene-1, 2,4-tri carboxylate, benzene-1,3,5-tricarboxylate have been widely used for the syntheses of coordination polymers. In this research, A new metal-organic framework formulated as [Co0.67Zn0.83(btc)(H2O)6] (1) was prepared and characterized by elemental analysis, and FT-IR spectroscopy. The single crystal analysis was used for determination of its structure. The structure was solved by direct methods with the Superflip program and refined by full-matrix least squares on F2 using the program Jana 2006. All hydrogen atoms were discernible in difference Fourier maps and could be refined to reasonable geometry. The complex (1) is crystallized in the monoclinic crystal system with I2 space group. Crystal data for complex (1): a= 6.4930 (1), b= 12.9426 (4), c= 16.1435 (5) [Å], ? = 89.951(2)[°], Z= 6.
