Carbonyl halides of the Group VI transition metals. X. Further dithiocarbamate derivatives of Molybdenum Halocarbonyls

Abstract

The changes effected in the stability of molybdenum carbonyl compounds of the types Mo(CO), dtc, and Mo(CO), dtc, (dtc = dialkyldithiocarbamate) and in their carbon monoxide carrying ability, by varying the alkyl group in the dithiocarbamate group, have been investigated. The oxidation of the carbonyl dithiocarbamate complexes by oxygen to the known molybdenum(v) complexes of the type Mo₂O₃ dtc, is reported. Extensive infrared and mass spectrometric studies on the latter compounds have been carried out. Attempts to isolate the corresponding tungsten compounds have been unsuccessful.
