✦ Synopsis

Mixed crystals PPh 4 [ReS(S 4 ) 2 ] 0,63 [ReO(S 4 ) 2 ] 0,37 were obtained from PPh 4 Cl, ReCl 5 and Na 2 S 4 in acetonitrile. Their crystal structure corresponds to the known structure of this kind of compound (space group P2 1 /n). In a similar reaction with ReBr 5 instead of ReCl 5 , PPh 4 [ReO(S 4 ) 2 ] was obtained in small yield. Its triclinic crystal structure was determined by X-ray crystallography (space group P1). It contains cation pairs (PPh 4 + ) 2 such as they have been found in many other instances. In contrast, the crystal structures of the mixed crystals and of one known modification of PPh 4 [ReS(S 4 ) 2 ] have PPh 4

• columns similar to compounds crystallizing in the space group P4/n, albeit in a severely distorted manner; their space group P2 1 /n is a subgroup of P4/n with a doubled unit cell. In another modification of PPh 4 [ReS(S 4 ) 2 ] (space group P2 1 /c) the columns are less distorted, but arranged in a different way.
