Bis[benzyl N'-(3-phenyl-prop-2-enyl-idene)hydrazinecarbodithio-ato-κN',S]copper(II).

The Cu(II) atom of the title complex, [Cu(C(17)H(15)N(2)S(2))(2)], lies on a twofold rotation axis, and is in a distorted tetra-hedral geometry with the two bidentate N(2)S(2) Schiff bases. In the crystal structure, the mol-ecules are inter-connected into chains along the c axis by weak C-H⋯S inter-molecular inter-actions. The crystal packing is further stabilized by C-H⋯π inter-actions.

Bis[benzyl N'-(3-phenyl-prop-2-enyl-idene)hydrazinecarbodithio-ato-κN',S]zinc(II).

In the title Zn(II) complex, [Zn(C(17)H(15)N(2)S(2))(2)], the Zn(II) atom lies on a twofold rotation axis. It exists in a tetra-hedral geometry, chelated by two deprotonated Schiff base ligands. The dihedral angle between each ligand is 71.48 (8)°. Mol-ecules are connected by weak C-H⋯S inter-molecular inter-actions into chains along the c axis. The crystal structure is further stabilized by C-H⋯π inter-actions involving the phenyl ring of the 3-phenyl-prop-2-enyl-idene unit.

Benzyl 3-[(E,E)-3-phenyl-prop-2-enyl-idene]dithio-carbazate.

The title compound, C(17)H(16)N(2)S(2), a dithio-carbazate derivative, adopts an EE configuration with respect to the C=C and C=N double bonds of the propenyl-idine group. The 3-phenyl-prop-2-enyl-idene and dithio-carbazate fragments lie essentially in the same plane, with a maximum deviation from that plane of 0.074 (2) Å, while the dihedral angle between the 3-phenyl-prop-2-enyl-idene and the benzyl group is 77.78 (7)°. In the crystal structure, mol-ecules are linked by an N-H⋯S hydrogen bond and a weak C-H⋯S inter-action involving the terminal thione S atom, forming dimers that are arranged into sheets parallel to the bc plane. The crystal structure is also stabilized by C-H⋯π inter-actions.
