Syntheses, Spectroscopy and X-Ray Crystal Structures of Luminescent Nitrido- and trans-Dioxo-rhenium(V) Complexes of Phosphines and Arsines
Reaction of and with a variety of phosphines and arsines, L, yielded the respective complex cations + and trans-+.The X-ray crystal structures of + and trans-+ have been determined: +, monoclinic, space group Cc, a = 10.362(2), b = 22.823(5), c = 21.363(6) Angstroem, beta = 92.74(2) deg, Z = 4; trans-+, monoclinic, space group Cc, a = 9.868(3), b = 22.608(5), c = 21.887(8) Angstroem, beta = 91.87(3) deg, Z = 4.A Re<*>N distance of 1.839(8) and Re=O distances of 1.785(8) and 1.766(8) Angstroem have been measured.The + and trans-+ complexes exhibit intense nu(Re<*>N) and nuasym (ReO2) streches at 1043-1049 and 785-790 cm-1, respectively.Excitation of solid samples of ClO4 and trans-ClO4 at 350-380 nm at room temperature results in yellow-green and orange emission, respectively.Both + and + exhibit intense long-lived room-temperature luminescence in fluid solutions.Concentration quenching has been observed for both + and + in MeCN (0.1 mol dm-3 NBu4PF6) with self-quenching rate constants of ca. 5.7 x 107 and 3.2 x 108 dm3 mol-1 s-1, respectively, and inherent lifetimes of ca. 15 and 0.9 mus at infinite dilution.All the trans-+ complexes exhibit room-temperature luminescence in MeCN.Cyclic voltammetric studies show that the + complexes display an irreversible reduction couple at Epc of ca. -2.1 to -2.4 and an irreversible oxidation couple at Epa of ca. +1.4 to +1.7 V vs. ferrocene-ferrocenium in MeCN (0.1 mol dm-3 NBu4PF6).Irreversible reduction and oxidation couples are also observed for the trans-+ species.A direct comparision of the photophysical and spectroscopic properties of + and trans-+ has been made.
