Abstract
The interactions of polyhydrides of molybdenum and tungsten of the typ e MH,(dppe), with proton donors of different protonation ability were studied with IR and UV spectroscopy in CH2Cl2. It was found that the f ormation of a molecular hydrogen-bonded complex (OH ... M) (1) is the first stage of protonation. An ionic H-complex of the type M(+)H ... O - (2) was formed as a result of proton transfer. Deprotonation of [WH5 (dppe)(2)](+)X(-) salt was found to proceed through the intermediate f ormation of complexes 2 and 1.
