摘要：

A new Mg(II)-Sm(III) heterometallic coordination polymer (Cp) with the formula [Sm-2(pydc)(6)Mg-3(H2O)(6)] . 11H(2)O (1) (H(2)pydc=pyridine-2,6-dicarbolylic acid) has been solvothermal synthesized by reacting pyridine-2,6-dicarbolylic acid, Sm(NO3)(3) . 6H(2)O, MgCl2 . 6H(2)O and imidazole at 393 K for 48 h. It was characterized by single-crystal X-ray diffraction, elemental analysis, IR and TGA. The results show that coordination polymer 1 exhibits a three-dimensional network structure and crystallizes in hexagonal crystal system, space group P6/mcc, with crystallographic data of a=15.4203(6) angstrom, b=15.4203(6) angstrom, c=15.2563(6) angstrom, alpha=beta=90 degrees, gamma=120 degrees, V=3141.7(3) angstrom(3), and Z=2. The twenty-member water cluster structure and topological structure of compound 1 were analyzed, and its luminescent properties were studied. It presents the characteristic emission spectra of Sm(III) ions.
