Synthesis, Crystal Structure and Thermoanalysis of Complex of Zn(Ⅱ) with Aminomethanesulfonic Acid-5-bromosalicylaldelyde Schiff Base

摘要

The title complex [Zn(L)(phen)(CH3OH)] (L= C8H6BrO4NS, aminomethanesulfonic acid 5-bromo-salicylaldelyde schiff base; phen = 1,10-phenanthroline) has been synthesized and characterized by X-ray diffraction method. The crystal belongs to monoclinic, space group P21/c with a = 1.8712(3), b = 1.38008(19), c = 0.83685(12) nm, β = 97.791 (2)°, Mr = 569.72, V = 2.1411(5)nm3,Z= 4, Dc = 1.767 g/cm3, μ = 3.151 mm-1, F(000) = 1144, the final R = 0.0402 and wR = 0.0885. The central Zn(Ⅱ) is six-coordinated by one nitrogen and two oxygen atoms from the Schiff base, two nitrogen atoms from 1,10-phenanthroline and one oxygen from methanol to form a distorted octahedral coordination geometry.
