Abstract

The reaction of S-benzyldithiocarbazate with 4-Methoxyacetophenone resulted in the formation of bidentate N,S Schiff base LH (LH = (E)-benzyl 2-(1-(4-methoxyphenyl)ethylidene) hydrazine-carbodithioate) which was further reacted with a copper(II) salt to yield bis-chelated cis-Cu(L)₂ inner complex. Both the desired LH and its cis-Cu(L)₂ complex have been characterized by XRD-crystal analysis. It is found that in the solid-state the LH existed in a thione tautomeric form, while the deprotonated L^- was found to chelate with the Cu(II) center via neutral nitrogen atom in azomethine. The ionic sulfur of thiol yielded a tetrahedral distorted square planar cis-Cu(L)₂ geometry. The IR, MS, XRD-powder and UV-vis-spectra of the free ligand, before and after bonding to Cu(II) center were carried out. Hirshfeld surface analysis (HSA) reflected the presence of the H...O and H…S strong hydrogen bonds as the main interactions in lattices of both LH and cis-Cu(L)₂ which correlated well with experimental XRD-packing result.
