title: {N,N'-Bis[1-(2-pyrid-yl)ethyl-idene]propane-1,2-diamine}-bis(thio-cyanato-κN)-nickel(II).
abstract: In the title complex, [Ni(NCS)(2)(C(17)H(20)N(4))], the Ni(2+) ion (site symmetry 2) is coordinated by the N,N,N,N-tetra-dentate Schiff base ligand and two thio-cyanate ligands, forming a distorted NiN(6) octa-hedral geometry, with the thio-cyanate N atoms in a trans orientation. The pendant methyl group of the central propane-1,2-diamine fragment of the ligand is statistically disordered over two sets of positions. In the crystal, weak aromatic π-π stacking between pyridine rings [centroid-centroid separation = 3.7081 (17) Å] may help to establish the packing.
