ABSTRACT: In the mononuclear title complex, [Ni(C(14)H(19)N(2)O(3))(NCS)], the nickel(II) atom is four-coordinated in a square-planar geometry by the O and N atoms of the tridentate Schiff base ligand and by the N atom of a thio-cyanate ligand. The crystal structure is stabilized by inter-molecular C-H⋯S and C-H⋯O hydrogen bonds, forming a three-dimensional network.
