Abstract
Trinuclear manganese complex [Mn3O(O2CC6H5)(6)( C3H4N2)(3)].C6H5CO2.0.5H(2) O was synthesied. The compound crystallizes in monoclinic space group P2(1) /C with a = 1.528 32(19) nm, b = 1.972 2(2) nm, c = 2.102 3(3) nm, beta = 9 2.597(3)degrees, V = 6.330 0(13) nm(3), Z = 4. In IR spectrum, the broad ba nd (10) is assigned to nu (as)(Mn3O), the doubly degenerate in - plane vibr ation of the central oxygen. Variable temperature (5 to 280 K) magnetic sus ceptibility exibits the expected weak antiferromagnetism, the magnetic susc eptibility data for the complex is fit. The fitting parameters is g = 2. 04 , J = - 2.34 cm(-1), F = 5.3 x 10(-3).
