Abstract: | (PPh4)2Cl2Re(N3S2)(μ‐NSN)(μ‐N≡ReCl3)]2 – a Rhenium(VII) Complex with a Nitrido, a Dinitridosulfato(II), and a Rhena‐3,5‐dithia‐2,4,6‐triazino Function The title compound has been prepared from PPh4ReVIICl4(NSCl)2] with N(SiMe3)3 in dichloromethane solution to give red‐brown single crystals, which were suitable for a crystal structure determination. As a by‐product PPh4ReNCl4] is formed. (PPh4)2Cl2ReVII(N3S2)(μ‐NSN)(μ‐N≡ReVIICl3)]2 ( 1 ): Space group P21/c, Z = 2, lattice dimensions at –80 °C: a = 1280.8(2), b = 1017.5(1), c = 2467.8(3) pm, β = 95.04(1)°, R = 0.049. The complex anion of 1 consists of a planar ReN3S2‐heterocycle which is connected with the second rhenium atom by a μ‐nitrido bridge as well as by a μ‐dinitridosulfato(II) ligand to form a planar Re2(N)(NSN) six‐membered heterocycle. This Cl2Re(N3S2)(μ‐NSN)(μ‐N≡ReCl3)]– unit dimerizes via one of the N‐atoms of the (NSN)4– ligand to give a centrosymmetric Re2N2 four‐membered ring. |
