✦ Synopsis

Professor Reinhart Ahlrichs zum 60. Geburtstag gewidmet (PPh 4 ) 2 [Cl 2 Re(N 3 S 2 )(l-NSN)(l-NºReCl 3 )] 2 ± a Rhenium(VII) Complex with a Nitrido, a Dinitridosulfato(II), and a Rhena-3,5-dithia-2,4,6-triazino Function Abstract. 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

: 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, b = 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 l-nitrido bridge as well as by a l-dinitridosulfato(II) ligand to form a planar Re 2 (N)(NSN) six-membered heterocycle. This [Cl 2 Re(N 3 S 2 )(l-NSN)(l-NºReCl 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.
