Spectroscopic Studies and Crystal Structure of Four-Coordinate Manganese(II) Chloride Complex

Abstract

High-spin new, manganese-(II) L2MnCl2, complex has been synthesized and its structure was elucidated by using elemental analysis, FT-IR, DTA-TG, 1H-NMR, 13C-NMR, and UV-Visible spectroscopic techniques. The structure of the compound has also been examined crystallographically. The title compound crystallizes in the triclinic space group P-1, with unit cell parameters: a = 11.354(1), b = 11.868(1), c = 12.080(1) Å, V = 1548.9(1) Å3, Dx = 1.270 g.cm−3, and Z = 2, respectively. The Mn atom was tetra-coordinated to form a distorted tetrahedral geometry by two oxygen atoms of L2 and two chloride atoms of MnCl2.4H2O in the complex.
