Crystal structure of di-aqua-bis-(2-chloro-pyridine-κN)bis-(thio-cyanato-κN)nickel(II).

The asymmetric unit of the title compound, [Ni(NCS)2(C5H4ClN)2(H2O)2], consists of one nickel(II) cation that is located on a center of inversion and one thio-cyanate anion, one water mol-ecule and one 2-chloro-pyridine ligand all occupying general positions. The Ni(II) cation is octa-hedrally coordinated by two terminal N-bound thio-cyanato ligands, two aqua ligands and two N-bound 2-chloro-pyridine ligands into discrete complexes. Individual complexes are linked by inter-molecular O-H⋯S and O-H⋯Cl hydrogen-bonding inter-actions into a layered network extending parallel to the bc plane. Weak inter-actions of types C-H⋯S and C-H⋯Cl consolidate the crystal packing.
