Poly[[μ-(3-amino­pyridine)-κ(2) N:N′-μ-chlorido-chlorido(N,N′-dimethyl­formamide-κO)nickel(II)] N,N′-dimethyl­formamide monosolvate]

The title compound, {[NiCl(2)(C(5)H(6)N(2))(C(3)H(7)NO)]·C(3)H(7)NO}(n), is a two-dimensional polymer in which the Ni(II) atom is coordinated by two N atoms from two 3-amino­pyridine ligands, one O atom from a dimethyl­formamide (DMF) group, one terminal Cl and two bridging Cl atoms in a distorted octa­hedral geometry. The Ni(II) atoms are bridged by the 3-amino­pyridine ligands [Ni⋯N = 6.7048 (3) Å] and Cl(−) atoms [Ni⋯N = 3.5698 (3) Å], forming (4,4) two-dimensional nets. The DMF solvent mol­ecule and the non-bridged Cl(−) ions participate in N—H⋯O and N—H⋯Cl hydrogen bonds with the amino groups.
