Project description: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.

{N,N-Dimethyl-N'-[1-(2-pyrid-yl)ethyl-idene]ethane-1,2-diamine-κN,N',N''}bis-(thio-cyanato-κN)copper(II).

Project description:The asymmetric unit of the title compound, [Cu(NCS)(2)(C(11)H(17)N(3))], consists of two crystallographically independent mol-ecules. In each mol-ecule, the Cu(II) ion is five-coordinated in a distorted square-pyramidal geometry wherein the basal plane is defined by the N,N',N"-tridentate Schiff base and one N-bound thio-cyanate ligand. The second N-donor thio-cyanate group, located at the apical site, completes the coordination environment. In the crystal, inter-molecular C-H⋯S and C-H⋯N hydrogen bonds link adjacent mol-ecules into infinite layers parallel to the ac plane. Intra-molecular C-H⋯N inter-actions are also observed.
