Crystal structure of S-hexyl (E)-3-(2-hy-droxy-benzyl-idene)di-thio-carbazate.

The title compound, C14H20N2OS2 [systematic name: S-hexyl (E)-2-(2-hy-droxy-benzyl-idene)hydrazine-1-carbodi-thio-ate], crystallizes with four independent mol-ecules (A-D) in the asymmetric unit. All four mol-ecules adopt an E conformation with respect to the C=N bond of the benzyl-idene moiety and have an intra-molecular O-H⋯N hydrogen bond generating an S(6) ring motif. In the crystal, the A and D mol-ecules are connected by a pair N-H⋯S hydrogen bonds, forming a dimer with an R 2 (2)(8) ring motif. In the case of mol-ecules B and C, they are linked to themselves by pairs of N-H⋯S hydrogen bonds, forming B-B and C-C inversion dimers with R 2 (2)(8) ring motifs.

The title compound, C32H30N4O2S4, consists of two Schiff base moieties, namely two S-benzyl-ß-N-(2-hy-droxy-phenyl-ethyl-idene)di-thio-carbazate groups, which are connected through an S-S single bond. These two moieties are twisted with respect to each other, with a dihedral angle of 87.88 (4)° between the S2C=N planes.

The dimers are further stacked in a column along the b axis through weak C-H⋯π inter-actions.

The title compound, [Cu2(C14H18N2OS2)2], is a binuclear copper(II) complex of an oxybenzyl-idenedi-thio-carbazate ligand. The ligand coordinates in a tridentate manner through N-, S- and O-donor atoms. Each O atom also bridges to a second Cu(II) ion to form the binuclear species. It has a central Cu2O2 rhomboid moiety and a metal-to-metal separation of 2.9923 (6) Å. In the crystal, the binuclear complexes stack along the a axis with all the hexyl chains located side-by-side, forming a hydro-phobic region.
