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

High-spin new, manganese-(II) L2MnCl2, complex has been synthesized and its structure was elucidated by using elemental analysis, FT-IR, DTA-TG, H-1-NMR, C-13-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) angstrom, V = 1548.9(1) angstrom(3), D-x = 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 L-2 and two chloride atoms of MnCl2 center dot 4H(2)O in the complex.
