Abstract
The title complex, [Ni(C13H20N2O2)2](NCS)2, consists of a centrosymmetric mononuclear four-coordinate nickel(II) complex cation and two thiocyanate anions. The Ni atom is located on an inversion center and is coordinated by two phenol O atoms and two imine N atoms from two equivalent Schiff base ligands, in a square-planar geometry. In the crystal structure, the amino H atoms are involved in N—H⋯O hydrogen bonds with the phenol and methoxy O atoms of the ligand, and in N—H⋯N hydrogen bonds with the N atoms of the thiocyanate anions, which sit above and below the Ni atom.
