    A new inorganic-organic nanohybrid based on a Keggin-type polyoxornolybdate and a copper(II) semicarbazone complex, namely [Cu-2(HL)(2)(PMo12O40)(OCH3)(2)(Cl)(H2O)]center dot 8CH(3)OH center dot 4H(2)O [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.
