The reaction of Re(CO)5Br with phosphorus-containing heterotridentate ligands HLnprepared by the condensation of 2-(diphenylphosphino)aniline with salicylaldehyde (HL1), 5-chlorosalicylaldehyde (HL2), 5-bromosalicylaldehyde (HL3), 5-nitrosalicylaldehyde (HL4), 5-methoxysalicylaldehyde (HL5) and 3-methoxysalicylaldehyde (HL6) yields complexes fac-(η3-Ln-P,N,O)Re(CO)3, where L represents the deprotonated heterotridentate ligand. These complexes are characterized by spectroscopic and crystallographic techniques. © 2001 Elsevier Science B.V.
