Bis(di-isopropylphenylphosphine)heptahydridorhenium(VII) (1) reacts with AgPF6, AgI, CuI, and HgCl2 to give the heterometallic complexes i2)2>2> (2) and i2)2>> (3); i2)2>> (4); i2)2>> (5); and i2)2>> (6) respectively, without loss of hydrogen.Similarly, i2)2> reacts with HgCl2 to give i2)2>>.Complex formation is accompanied by only subtle changes in the hydride (1)H n.m.r. shifts ( ( Z = 2), with lattice parameters a = 13.188(6), b = 16.014(6), c = 14.827(6) Angstroem, α = 112.47(3), β = 101.03(3), and γ = 90.65(3)deg.The structure was solved and refined to R = 0.048 (R' = 0.047) for 4 452 reflections having 2Θ 50 deg (Mo-KαX-radiation) collected at 200 K.The complex cation comprises a silver atom and two Re(PPhPri2)2 fragments arranged linearly (Re-Ag-Re 172deg, mean Re-Ag 2.873 Angstroem ).No evidence of the hydride ligands was found from the diffraction study.
