Organogermanium derivatives of dithiophosphoric acid of general formula R(4-n)Gen, where n = 1-3, R = Me, Ph and R' = Me, Et, have been prepared and characterized by means of 1H, 13C NMR and vibrational spectroscopy and mass spectrometry.The spectroscopic results indicate that the dithiophosphate groups are monodentate and that an approximate tetrahedral geometry about the germanium atom is maintained.This is in part confirmed by a preliminary X-ray crystallographic determination of PhGe3, whose crystals are orthorhombic, space group Pn2₁a, a 13.673(4), b 14.566(3), c 13.154(3) Angstroem, V 2620(1) Angstroem³ and Z = 4 from 1225 observed reflections 3?(I)>.
