Synthesis and X-ray crystal structure of an oxorhenium(V) complex with a double Schiff base

The reaction of the double Schiff bases, RL, formed from 2,6-diformyl-4-methyl-phenol and p-RC6H4NH2 (R = H, Me, OMe, Cl) with ReOCl3(PPh3)2 afforded red coloured complexes of the type ReVOCl3(RL). The X-ray structure of the R = Me complex (crystal data: ReOCl3(MeL) · CH2Cl2, triclinic, space group P1, a = 8.736(2), b = 10.632(3), c = 16.575(5) A, α = 104.64(2)°, β = 93.22(2)°, γ = 110.57(2)°, V = 1376.6(7) A3, Z = 2, R = 3.06%, RW = 3.51%) revealed meridional chloro coordination in an ReOCl3 (ON) coordination sphere. The RL ligand binds in the bidentate ON mode, the second imine function occurring in the protonated form (N-H...O hydrogen bonding). IR and 1H NMR data indicate that the solid-state structure is substantially retained in solution. The complexes display a quasi-reversible ReVIO/ReVO couple whose potential depends on the R substituent.
