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-amino-pyridine ligands, one O atom from a dimethyl-formamide (DMF) group, one terminal Cl and two bridging Cl atoms in a distorted octa-hedral geometry. The Ni(II) atoms are bridged by the 3-amino-pyridine 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 mol-ecule and the non-bridged Cl(-) ions participate in N-H⋯O and N-H⋯Cl hydrogen bonds with the amino groups.
