Abstract: Various potential bidentate hemilabile ligands with different aliphatic backbones, such as Ph2PCH2CH2COOC2H5(a ),Ph2PCH (CH3)COOCH3 (b),  Ph2PCH2OCH3 (c), Ph2PCH2CH2 OC2H5 (d), Ph2PCH2CH2SC2H5(e) react with [RuCl2(PPh3)3] in 3: 1 molar ratio to produce complexes of the type [RuCl2(P~X)2(P∩X)] (1a-e) [where P~X = η1 - (P) coordinated; P∩X = η2- (P, X) coordinated ligand; X = O, S]. On the other hand, reaction of a ligand containing an aromatic backbone unit such as o- Ph2PC6 H4COOC2H5 with [RuCl2(PPh3)3] produces a bis-chelate complex [RuCl2(P∩O)2] (2). The complexes have been characterized by elemental analysis, IR, 1H, and 31P{1H}  NMR spectroscopy.
