Deskripsi
This work is concerned with the synthesis of neutral dioxovana-dium(V) and dioxomolybdenum(VI) complexes with tridentate ONN pyri-doxal S-methylisothiosemicarbazone (PLITSC) of the respective formulas [VO2(PLITSC–H)]•2H2O and [MoO2(PLITSC–2H)]. Structural X-ray analysis of the vanadium complex showed that it has an almost ideal square-pyramidal structure, while the molybdenum complex is supposed to have a polymeric octahedral structure. In addition to elemental analysis, both complexes were characterized by conductometric and magnetometric measurements, as well as by IR, UV–Vis, 1H- and 13C-NMR spectra.
