Poly[[bis(benzimidazole)manganese(II)]-di-μ-1,5-dicyanamido

Abstract

In the crystal structure of the title complex, [Mn(C2N3)2(C7H6N2)2] n or [Mn(dca)2(bim)2] n , where dca is dicyanamide and bim is benzimidazole, each MnII atom is located on a center of symmetry and is in a six-coordinated distorted octahedral environment. Four N atoms from four dca ligands fill the equatorial positions, and two N atoms from two bim ligands occupy the axial positions. The dicyanamide ligands adopt an end-to-end coordination mode and link the Mn atoms to form a two-dimensional network.
