Abstract

The title compound, (4-aminophenylimido)trichloro[2-(4-chlorophenyliminomethyl)pyridine]rhenium(V), [Re-(NC₆H₄NH₂)Cl₃(ClA)], where ClA is N-(p-chlorophenyl)pyridine-2-aldimine (p-ClC₆H₄N=CHC₅H₄N), was synthesized by reacting the corresponding oxo complex, [ReOCl₃(ClA)], or the corresponding phosphine oxide complex, [Re(OPPh₃)Cl₃(ClA)], with p-phenylenediamine in toluene. The structure determination revealed that the ReCl₃N₃ coordination sphere is severely distorted from octahedral geometry and that it has a meridional ReCl₃ fragment. The Re - N - C angle in the imide part is nearly linear and the Re - N_imide bond can be considered to be triple bond in character. The Re atom is distorted towards the imide N atom by 0.29 Å from the equatorial Cl₃N_imine plane. The Re - N_pyridine bond is longer by 0.15 Å than the Re - N_imine bond due to the trans influence of the imide fragment.
