A new complex of tris(2-benzimidazylmethyl)amine (NTB) with manganese(II) was synthesized. Single crystal X ray diffraction studies show that this new compound belongs to monoclinic, space group P2 1/c with a = 1.423 8(7) nm, b = 2.480 2(3) nm, c =1.697 7(7) nm, V = 5.989 3nm 3 and Z = 4 The crystal structure was solved by heavy atom and Fourier synthesis methods, the structure was refined to R = 0 07 The coordinated number of Mn 2+ is five with a distorted tri nal bipyramid geometry. The quantum chemistry calculation shows that Mn 2+ cation locates itself in the middle of the negative charge hole formed by five nitrogen atoms.
