چکیده
The mol-ecules of the title compound, C16H18N2, exists in a trans conformation with respect to the C=N bond [1.270 (3) Å]. The least-squares plane of the di-methyl-amino group makes a dihedral angle of 1.3 (2)° with the ring to which it is attached. The dihedral angle between the two aromatic rings is 11.70 (2)°. The crystal structure features weak C-H⋯π inter-actions.

The asymmetric unit of the title compound, C17H20N4S, contains two independent mol-ecules, the main difference between them being the dihedral angles between the benzene rings [19.99 (17) and 9.72 (17)°]. The mol-ecules both have a trans conformation about the C=N double bond and intra-molecular C-H⋯S and N-H⋯N hydrogen bonds are observed in both mol-ecules. In the crystal, mol-ecules are linke...

In the title complex, [Cu(C16H24N3S2)2], the Cu(II) atom is coordinated by two azomethine N and two thiol-ate S atoms of the chelating Schiff base ligands, resulting in a distorted square-planar coordination environment. The S-Cu-N chelating angle is of 84.41 (5)°. The Cu(II) atom is located on a crystallographic inversion centre, leading to a trans configuration of the N,S-chelating ligands.
