摘要

The complex [Mn(PMBP)(2)(CH3OH)(2)] of manganese(II) with 1-phenyl-3-methyl- 4-benzoyl-5-pyrazolone (PMBP) was prepared and characterized by elemental analysis, thermal analysis, IR. The crystal structure of the complex determined by single crystal X-ray analysis, indicates that PMBP is a bidentate ligand in the complex and Mn(II) atom is six-coordinated and is in a meridional octahedral environment. The compound crystallizes in the monoclinic system, space group P-2(1)/c, with a = 11.038(10) angstrom, b = 16.254(15) angstrom, c = 9.540(9) angstrom, alpha = 90.00 degrees, b = 105.112(10)degrees, c = 90.00 degrees, V = 1,652(3) angstrom(3), D-x = 1.354 g cm(-3) and Z = 2. The thermal decomposition kinetics of the complex was investigated under nonisothermal conditions using the Achar differential method and the Coats-Redfern integral method.
