(PPh 4 ) 2 [Cl 2 Re(N 3 S 2 )(μ‐NSN)(μ‐N≡ReCl 3 )] 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 PPh 4 [Re VII Cl 4 (NSCl) 2 ] with N(SiMe 3 ) 3 in dichloromethane solution to give red‐brown single crystals, which were suitable for a crystal structure determination. As a by‐product PPh 4 [ReNCl 4 ] is formed. (PPh 4 ) 2 [Cl 2 Re VII (N 3 S 2 )(μ‐NSN)(μ‐N≡Re VII Cl 3 )] 2 ( 1 ): Space group P2 1 /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 ReN 3 S 2 ‐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 Re 2 (N)(NSN) six‐membered heterocycle. This [Cl 2 Re(N 3 S 2 )(μ‐NSN)(μ‐N≡ReCl 3 )] – unit dimerizes via one of the N‐atoms of the (NSN) 4– ligand to give a centrosymmetric Re 2 N 2 four‐membered ring.
