Crystal structure of diaquabis(2-chloropyridine-κN)bis(thiocyanato-κN)nickel(II)
Abstract
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 thiocyanate anion, one water molecule and one 2-chloropyridine ligand all occupying general positions. The NiII cation is octahedrally coordinated by two terminal N-bound thiocyanato ligands, two aqua ligands and two N-bound 2-chloropyridine ligands into discrete complexes. Individual complexes are linked by intermolecular O—H...S and O—H...Cl hydrogen-bonding interactions into a layered network extending parallel to the bc plane. Weak interactions of types C—H...S and C—H...Cl consolidate the crystal packing.
