Synthesis and Crystal Structure of a Novel 3D Sm(III) Coordination Polymer with Mixed Ligands
Abstract:
The coordination polymer, [Sm2(HPyImDC)2Ox (H2O)2·6H2n [H3PyImDC = 2-(pyridine-3-yl)-1H-4,5-imidazoledicarboxylic acid, Ox = oxalate], has been synthesized under hydrothermal conditions and characterized by elemental analysis, FT-IR and single crystal X-ray diffraction. It crystallizes in monoclinic, space group C2/c with a = 28.166(6), b = 6.9970(14), c = 16.655(3) Å, V = 2685.4(9) Å3, Z = 4, Dc = 2.298 g/cm3, μ(MoKα) = 4.428 mm-1, F(000) = 1852, the final R = 0.0412 and wR = 0.1010. The complex forms a three-dimensional (3D) framework structure.
