Hydrothermal synthesis and crystal structure of a layered coordination polymer: [Zn3(C2O4)3(4,4 '-bipy)4](n) (4,4 '-bipy=4,4 '-bipyridine)

摘要

An interesting metal-organic coordination polymer {[Zn-3(C2O4)(3)(4,4'-bipy)(4)]}(n) 1 has been hydrothermally synthesized and characterized by elemental analyses, IR spectrum, TG analysis, and single-crystal X-ray diffraction. Compound I crystallizes in the monoclinic system, space group P2(1)/c, a = 16.264(3) Angstrom, b = 15.603(3) Angstrom, c = 16.343(3) Angstrom, beta = 94.13(3)degrees, V = 4136.5(14) Angstrom(3), Z = 4, R1 = 0.0554, wR(2) = 0.1217. Compound 1 exhibits a 2D network, which consists of infinite zinc (II) oxalate chains connected to each other by a half of 4,4'-bipy acting as bridging ligands, while the other half of 4,4-bipy just does as terminal ones.
