2-[(1)-[()-2-({[(1)-[()-2-[(2-Hy-droxy-phen-yl)methyl-idene]hydrazin-1-yl-idene]({[(4-methyl-phen-yl)meth-yl]sulfan-yl})meth-yl]disulfan-yl}({[(4-methyl-phen-yl)meth-yl]sulfan-yl})methyl-idene)hydrazin-1-yl-idene]meth-yl]phenol: crystal structure, Hirshfeld surface analysis and computational study.

The complete mol-ecule of the title hydrazine carbodi-thio-ate derivative, CHNOS, is generated by a crystallographic twofold axis that bis-ects the di-sulfide bond. The mol-ecule is twisted about this bond with the C-S-S-C torsion angle of 90.70 (8)° indicating an orthogonal relationship between the symmetry-related halves of the mol-ecule.

Synthesis, characterization and biological activity of Cu(II), Zn(II) and Re(I) complexes derived from S-benzyldithiocarbazate and 3-acetylcoumarin.

Cu(II), Zn(II) and Re(I) complexes have been synthesized with the Schiff base, N'-[1-(2-oxo-2H-chromen-3-yl)-ethylidene]-hydrazinecarbodithioic acid benzyl ester (SBCM-H) which was prepared by condensation of S-benzyldithiocarbazate and 3-acetylcoumarin. The metal complexes were characterized on the basis of various physico-chemical and spectroscopic techniques including elemental analysis and electrochemical studies, and FT-IR, UV-Vis, NMR, EPR and mass spectroscopy. The Schiff base was found to behave as a bidentate ligand coordinating with Cu(II) and Zn(II) in the thiolate form with 1:2 metal to ligand stoichiometry.
