This work is concerned with the synthesis of neutral dioxovanadium(V) and dioxomolybdenum(VI) complexes with tridentate ONN pyridoxal S-methylisothiosemicarbazone (PLITSC) of the respective formulas [VO2(PLITSC-H)]center dot 2H(2)O 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, H-1- and C-13-NMR spectra.
