Abstract
In title complex, [Mn(C2N3)2(C10H8N2)2], the MnII ion is coordinated in a slightly distorted octahedral geometry by six N atoms. Four of the N atoms are from two chelating bipyridine ligands and two are from a pair of cis-coordinated dicyanamide ligands. The dihedral angle formed by the mean planes of the bipyridine rings is 85.93 (14)°. The central N atom of one of the dicyanamide ligands was refined as disordered over two sites with equal occupancies.
