Methyl-and ethyl-gallium complexes with dialkyl-dithio,-monothio and oxy-phosphate ligands have been prepared by the reaction of R_3-nGaCl_n(R= Me or Et;η = 1 or 2) with the salt of the phosphoric acid.All the complexes are colorless oil/paste and are sensitive to oisture.These complexes have been characterized by elemental analysis,IR and NMR (¹Η,¹³C,³¹P) spectroscopy.
