title: catena-Poly[[dicyanamido(5,5'-dimethyl-2,2'-bipyridine-kappa2N,N')copper(II)]-mu-dicyanamido-kappa2N1:N5].
abstract: In the crystal structure of the title compound, [Cu(C(2)N(3))(2)(C(12)H(12)N(2))](n), the Cu(II) atom adopts a distorted square-pyramidal geometry, the basal plane of which is formed by two N atoms of the bipyridine ligand, one N atom of a bidentate dicyanamide anion and one N atom of a monodentate dicyanamide anion [Cu-N = 1.9760(15)-2.0157(15)A]. The apical position is occupied by an N atom of a bidentate dicyanamide anion, located 2.2468(16)A from the Cu atom, thus forming a one-dimensional polymeric chain.
