Abstract:
The reaction of ReBr4, Te and TeBr4 in SiBr4 as solvent in a sealed glass ampoule at 150 degrees C yields black crystals of Re2Te6Br10. As the X-ray crystal structure determination shows [monoclinic, P2(1), Z = 2, a = 1127.5(1), b = 861.85(9), c = 1231.0(2)pm, beta = 105.47(9)degrees] the structure consists of discrete dinuclear complexes. A Re-Re dumb-bell with d(Re-Re) = 279.9 pm is coordinated by a mu-Te-2 group and two mu-TeBr groups. Additionally, each Re atom is coordinated to two terminal bromine atoms and a TeBr2 ligand leading to the formula [Re2Br4(Te-2)(TeBr)(2)(TeBT2)(2)] Re2Te6Br10 is one of only a few compounds known in the ternary system Re/Te/Br.
