Poly[[μ-(3-aminopyridine)-κ2N:N′-μ-chlorido-chlorido(N,N′-dimethylformamide-κO)nickel(II)] N,N′-dimethylformamide monosolvate]

Abstract

The title compound, {[NiCl2(C5H6N2)(C3H7NO)]·C3H7NO}n, is a two-dimensional polymer in which the NiII 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 NiII 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.
