Popis:	A reaction was carried out to make trans-[Re2{O2C-3,5-(OH)2C6H3}2Br2(dppm)2] (dppm is Ph2PCH2PPh2). No trans-[Re2{O2C-3,5-(OH)2C6H3}2Br2(dppm)2] was isolated, how­ever, and a very small quantity of crystalline [Re(dppm)3][ReO4] was obtained after several months. A product of decomposition by disproportionation of a complex of di­rhenium, [Re(dppm)3]ReO4 is an ionic compound that contains a complex cation of ReI bonded to three chelating dppm ligands. Although complexes that contain three chelating dppm ligands are very rare, this is the second time [Re(dppm)3]+ has been observed and characterized struct­urally. In 2000, [Re(dppm)3]+, with I− as the counter-ion, was structurally characterized [Rivero et al. (2000). Polyhedron, 19, 2249–2254]. The Re—P distances in the compound we characterized range from 2.408 (3) to 2.473 (3) A, and the P—Re—P angles, associated with the chelate rings, range from 68.22 (12) to 70.04 (12)°. These values are very similar to those reported by Rivero et al. (2000).
