Sažetak

The synthesis of two monomeric molybdenum(VI) Schiff base complexes derived from N-phenyl-2-hidroxy-1-naphthaldimine and N-benzyl-2-hidroxy-1-naphthaldimine: [MoO2(C5H7O2)(OCH3)(2-OC10H6CH=NHC6H5)] (I) and [MoO2(C5H7O2)(OCH3)(2-OC10H6CH=NHCH2C6H5)] (II) described in this paper are the first examples in which potentially bidentate Schiff bases are monodentately bonded to molybdenum as zwitterionic ligands. The structure of complex I was determined by X-ray analysis. Within the same ligand, the hydrogen atom attached to nitrogen forms an intramolecular hydrogen bond of 2.548(2) Å with the oxygen atom coordinated to molybdenum. The octahedral coordination of molybdenum is completed by two oxo-oxygens, two acetylacetonato oxygens and one methoxy oxygen. The compounds were characterized by chemical analysis, IR spectroscopy and single crystal structure determination.
