Abstract : The bidentate N-donor ligand 2,2'-biquinoline C18H12N2 [I] reacts with the salt [Ru(CO)2Cl2)]n [II] in (1:1) mole in THF. This gives a stable yellow crystallized solid dichlorodicarbonyl 2,2'-biquinoline ruthenium (II) [Ru(CO)2Cl2C18H12N2] complex [III]. Similarly treatment of molybdenum hexacarbonyl with 2,2'-biquinoline in (1:1) mole ratio in toluene gives a very dark violet crystals of tetracarbonyl 2,2'-biquinoline molybdenum (0) [Mo(CO)4C18H12N2] complex [IV]. Spectroscopic data indicates that metal atoms in these complexes are coordinated through both the N-atoms of 2,2'-biquinoline thus maintain an octahedral geometry of these complexes. The complex (IV) on treatment with triphenylphosphine in (1:1) mole ratio gives mono substituted tricarbonyl triphenylphosphine 2,2'- biquinoline molybdenum(0) complex (V). Similarly the complex (IV) on treatment with (1:2) mole ratio with triphenylphosphine or with large excess of triphenylphosphine gives disubstituted dicarbonyl bistriphenylphosphine molybdenum(0) complex (VI). All the complexes were characterized by IR & 1HNMR spectroscopy, and by elemental analysis.
