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

Abstract

High-spin new, manganese-(II) L <inf>2</inf>MnCl <inf>2</inf>, 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)Å 3, D <inf>x</inf> = 1.270g.cm -3, and Z = 2, respectively. The Mn atom was tetra-coordinated to form a distorted tetrahedral geometry by two oxygen atoms of L <inf>2</inf> and two chloride atoms of MnCl <inf>2</inf>.4H <inf>2</inf>O in the complex. © 2012 Copyright Taylor and Francis Group, LLC.
