The reaction between PCl 3 and ReCl 5 yielded at 200 °C the ionic tetrachlorophosphonium dirhenium nonachloride, (PCl 4 )[Re 2 Cl 9 ]. Single crystal X‐ray diffraction analysis revealed a monoclinic unit cell: a = 8.616(3) Å, b = 10.449(4) Å, c = 9.397(3) Å, β = 99.72(3)°, V = 833.9(5) Å 3 , Z = 2, sp. gr. P2 1 /m, wR 2 = 0.1083 and R 1 = 0.0527. The ionic compound is built from tetrahedra PCl 4 + and face‐sharing bioctahedra Re 2 Cl 9 – . The Re–Re distance, 2.724 Å, indicates the presence of direct Re‐Re interaction.
