Sažetak
The [Mo_2O_2S_2(OSCC_6H_5)_2] (1) has been prepared either by the reaction of [Mo_2O-3(C_5H_7O_2)_4] or of [Mo_4Cl_2O_6(O_2CCH_3)_6]ˇ(CH_3CO)_2O with thiobenzoic acid. The product was then used to prepare two complexes of the general formula [Mo_2O_2S_2(OSCC_6H_5)_2L_2] (where L = pyridine (2) or gama-picoline (3)). All complexes were characterized by elemental analyses, IR spectra and magnetic measurements. The structures of (2) and (3) were proved by X-ray structure analysis. Both complexes are dinuclear containing Mo_2O_2S_2 core with two Mo atoms linked by a Mo-Mo single bond. The Mo atoms are octahedrally coordinated by oxo-oxygen, two bridging sulfido-sulfurs, one pyridine (or gama-picoline)-nitrogen and thiobenzoato-sulfur and thiobenzoato-oxygen atoms.
