In the title coordination polymer, [Cd(C(7)H(4)N(3)O(2))(2)(C(3)H(7)NO)(2)](n), the Cd(II) atom, lying on an inversion center, is six-coordinated in a distorted N(4)O(2) octa-hedral geometry. The N atoms of the 4-nitrophenylcyanamide anions form the equatorial plane and the O atoms of the dimethyl-formamide mol-ecules occupy the axial positions. The anions act as bridging ligands, connecting th...

The title compound, [Co(C(2)N(3))(2)(C(3)H(7)NO)(2)](n), is a triclinic polymorph of the previously reported monoclinic structure [Tong et al. (2003 ▶). Acta Cryst. E59, m405-m407]. The Co(II) ion lies on an inversion centre and adopts an almost regular octa-hedral N(4)O(2) coordination geometry. Adjacent Co(II) atoms are connected by two bridging dicyanamide ligands, resulting in the formation...
