Notizen: The title compounds were prepared and their Raman spectra were measured, assigned and compared with that of PH3GaCl3. The frequencies of the pyramidal GaCl3 unit are sensitive to the basicity of the phosphine ligand. Modes ν(Gap), appreciably coupled to Ph-P stretching vibrations, are located at 316, 260 and 182 cm-1 as medium to weak bands in the spectra of PhPH2GaCl3, Ph2 PHGaCl3 and Ph3PGaCl3, respectively. The P—H stretching and bending modes give rise to medium to strong Raman bands, and these frequencies increase on coordination.
