Several complexes of the type, [M{S2CNR}3](1)(M=Ga or In;R=CH2CH2OCH2CH2, CH2CH2N(Me)CH2CH2),[MCl2{S2CN(CH2CH2)2O}](2) (M=Ga or In), [MCl{S2CN(CH2CH2)2O}2](3) (M=Ga or In),[Ga{S2CN(CH2-CH2)2O}{S2P(OR)2}2](4) (R=Et, Pri) and [M{S2CNR}{(SCH2CH2)2O}] (5) (M=Ga or In; R=CH2CH2OCH2CH2,CH2CH2N(Me)CH2CH2) ave been prepared. All the complexes were characterized by elemental analysis, IR and NMR (1H,13C{1H}) spectroscopy.71Ga NMR chemical shifts and half line widths are influenced by the coordination number of gallium and the substituents on the ligand moiety. Single crystal X-ray structures of two complexes [M{S2CN(CH2CH2)2O}3] (M=Ga, In)have been determined.
