Bis(di-2-pyridyl-amine-κN,N')bis-(thio-cyanato-κN)nickel(II).

The mononuclear neutral title complex, [Ni(NCS)(2)(C(10)H(9)N(3))(2)], shows a cis-octa-hedral geometry around the Ni(II) ion, formed by two chelating di-2-pyridyl-amine (Hdpa) ligands and two thio-cyanate anions. Both amine H atoms are involved in N-H⋯S hydrogen bonding, resulting in the formation of layers of inter-linked mol-ecules parallel to the ab plane, which are further held together by weak π-π inter-actions between adjacent complexes, involving one ring of each dipyridyl-amine unit [centroid-centroid distance = 3.777†(4)†à ], forming a three-dimensional assembly.
