Abstract

Two basic halides of molybdenum(111), namely MoOF(H2O)3 and MoOCl(H2O)3 (some samples containing additional loosely bound water), were investigated by absorption spectroscopy in the range 200-50000 cm-1, and by magnetic susceptibility measurements over a temperature range of 100-300 K. Infrared spectra showed bands at about 670 and 1600 cm-l, but not in the range 800-1100 cm-1. Electronic spectra showed poorly defined bands superimposed on strong general absorption. Very weak paramagnetism was observed: this was field dependent. The results are interpreted to show the compounds to be oxygen-bridged polymers [MOX(H2O)3O]n, rather than species containing Mo=O or Mo-0-H groups.
