(PPh 4 ) 2 [(SN)ReCl 3 (μ‐N)(μ‐NSN)ReCl 3 (THF)] – a Nitrido‐Thionitrosyl‐Dinitridosulfato‐Complex of Rhenium The title compound has been prepared from PPh 4 [Re VII Cl 4 (NSCl) 2 ] with excess N(SiMe 3 ) 3 in dichloromethane solution to give red‐brown single crystals after recrystallisation from acetonitrile/THF solutions. As a by‐product PPh 4 [ReNCl 4 ] is formed. (PPh 4 ) 2 [(SN)ReCl 3 (μ‐N)(μ‐NSN)ReCl 3 (THF)] ( 1 ): Space group P2 1 /n, Z = 4, lattice dimensions at –80 °C: a = 1024.1(1), b = 2350.2(1), c = 2315.4(2) pm, β = 94.09(1)°, R 1 = 0.0403. In the complex anion of 1 the rhenium atoms are connected by an asymmetric Re≡N–Re bridge as well as by a (NSN) 4– ‐bridge to form a planar Re 2 N(NSN) six‐membered heterocycle. Both rhenium atoms are coordinated by three chlorine atoms, one of them by a thionitrosyl ligand, the other one by the oxygen atom of a thf molecule.
