Tricarbonylrhenium(I) Complexes with Tridentate Schiff Bases

Potentially tridentate, phosphine-containing Schiff bases with P,N,O and P,N,P donor sets have been prepared from 2-(diphenylphosphino)benzaldehyde, salicylaldehyde, 2-aminophenol 2-((diphenylphosphino)phenyl)methylamine reacted (NEt4)2[Re(CO)3Br3] in methanol. Deprotonation the formation of neutral [Re(CO)3(L)] complexes tridentate coordination has obtained for salicylidene derivatives, while potential ligand L3 forms [Re(CO)3Br(L3)] base a bidentate bonding mode. The cationic [Re(CO)3(L3)]+ complex tripodal organic could be achieved by addition Ag(PF6) to reaction mixture. rhenium(I) were studied spectroscopically X-ray diffraction.
