Synthesis, spectroscopic and crystal structure investigation of [Cu(bzsmp)2Cl2];{bzsmp = 2-benzylsulfanyl-5-(2-methoxyphenyl)-1,3,4-oxadiazole}: cyclization of N2-[bis(benzylsulfanyl)methylene]-2-methoxybenzohydrazide to 2-benzylsulfanyl-5-(2-methoxypheny

The ligand N2-[bis(benzylsulfanyl)methylene]-2-methoxybenzohydrazide (N2-bmbh) (1) on reaction with CuCl2.2H2O yielded the mononuclear complex [Cu(bzsmp)2Cl2] (2) (2-benzylsulfanyl-5-(2-methoxyphenyl)-1,3,4-oxadiazole, bzsmp). Complex 2 has been characterized by analytical, spectroscopic and X-ray data. X-ray study of 2 reveals that the cyclized ligand 2-benzylsulfanyl-5-(2-methoxyphenyl)-1,3,4-oxadiazole (bzsmp) acts as neutral bidentate ligand to form six membered chelate ring and the presence of C–H⋯π (face to edge) and C–H⋯S and two type of C–H⋯Cl weak interactions.

The ligand [N2-Hbmbh] (1) {N2-[bis(benzylsulfanyl)methylene]-2-methoxybenzo-hydrazide in MeOH solvent on reaction with CuCl2 · 2H2O, underwent cyclization to afford the complex [Cu(bzsmp)2Cl2] (2) {bzsmp = 2-benzylsulfanyl-5-(2-methoxy-phenyl)-1,3,4-oxadiazole}.Figure optionsDownload as PowerPoint slide
