A new inorganic–organic nanohybrid based on a Keggin-type polyoxomolybdate and a copper(II) semicarbazone complex, namely [Cu2(HL)2(PMo12O40)(OCH3)2(Cl)(H2O)]·8CH3OH·4H2O [HL = pyridine-2-carbaldehyde semicarbazone] (1) was synthesized by a sonochemical method. Single crystals of 1 were synthesized with the branched tube method. The nanohybrid 1 was characterized using FT-IR, PXRD, FESEM, TEM, EDX, UV–Vis, TG-DTA analysis and single-crystal X-ray diffraction. Single-crystal X-ray diffraction reveals that the PMo12O403?cluster acts as a bidentate inorganic ligand and coordinates two symmetrically equivalent [Cu(Cl)0.5(HL)(OCH3)(H2O)0.5] complexes. SEM and TEM images confirmed a highly porous plate-like morphology of the nanohybrid sample. To the best of our knowledge, 1 represents the first example of a hybrid based on POMs and semicarbazone Schiff base complexes. The photocatalytic properties of the nanohybrid 1 were investigated in detail and the results of the photocatalytic experiments show it can be used as an efficient and recoverable photocatalyst for the complete degradation of the cationic dyes methylene blue (MB) and rhodamin B (RhB).

A tridentate NNO donor Schiff base ligand HL [HL: C5H 4NCH=NNHCONH2] was obtained by condensation of pyridine 2-carbaldehyde with semicarbazide. The HL and azide ligands with Cr(III) and Cu(II) ions have been used to synth

Substituted semicarbazones/thiosemicarbazones and their copper complexes have been prepared and several single crystal structures examined. The copper complexes of these semicarbazone/thiosemicarbazones were prepared and several crystal structures examined. The single crystal X-ray structure of the pyridyl-substituted semicarbazone showed two types of copper complexes, a monomer and a dimer. We also found that the p-nitrophenyl semicarbazone formed a conventional ‘magic lantern’ acetate-bridged dimer. Electron Paramagnetic Resonance (EPR) of several of the copper complexes was consistent with the results of single crystal X-ray crystallography. The EPR spectra of the p-nitrophenyl semicarbazone copper complex in dimethylsulfoxide (DMSO) showed the presence of two species, confirming the structural information. Since thiosemicarbazones and semicarbazones have been reported to exhibit anticancer activity, we examined the anticancer activity of several of the derivatives reported in the present study and interestingly only the thiosemicarbazone showed activity while the semicarbazones were not active indicating that introduction of sulphur atom alters the biological profile of these thiosemicarbazones.
