•Application of a bulky bis(imino)pyridine ligand, 2,6-iPr2C6H = N=CPh}2(NC5H3).•Bidentate coordination to yield fac-tricarbonylhalo Re(I) complexes.•Triflate complex obtained by reaction with AgOTf and opens potential reactive site on Re.
Reported in this contribution are the synthesis and characterization of bidentate bis(imino)pyridine Re(I) complexes 2,6-{2,6-iPr2C6H3N = CPh}2(NC5H3)Re(CO)3X (X = Br (2), Cl (3), and OSO2CF3 (4)). Compounds 2 and 3 were prepared by direct reaction of bis(imino)pyridine ligand 2,6-{2,6-iPr2C6H3N = CPh}2(NC5H3) (1) with Re(CO)5X (X = Br, Cl) in toluene solution at 100 °C. Further treatment of 2 or 3 with Ag(OSO2CF3), in both instances, resulted in the formation of 4. Molecular structures of the new compounds (2, 3, and 4) were established by single crystal X-ray diffraction, and confirmed by elemental analysis and NMR studies.
