Investigation of bi- and trinuclear thiochloride complexes of molybdenum by vibrational spectroscopy
The IR and Raman spectra of bi- and trinuclear thiochloride complex of molybdenum have been studied. The following compounds containing the /sup 92/Mo and /sup 100/Mo isotopes have been synthesized: H/sub 2/(Mo/sub 2/S/sub 4/Cl/sub 8/) x 6H/sub 2/O, Cs/sub 2/(Mo/sub 2/S/sub 4/Cl/sub 9/), Mo/sub 2/S/sub 4/Cl/sub 6/, and Mo/sub 2/S/sub 4/Cl/sub 4/. An analysis of the normal modes of vibration of the (Mo/sub 2/S/sub 4/Cl/sub 8/) and (Mo/sub 2/S/sub 4/Cl/sub 6/) fragments has been carried out. The force constants of the Mo-Mo, Mo-S, and Mo-Cl bonds have been determined, and the values before and after the transition from the trinuclear complex to the binuclear complex have been compared. The nature of the chemical bonding in the complexes of molybdenum with dichalogenide ligands has been discussed.
