3)-CHLORO-TETRA-MU(3)-TELLURO-OCTOHEXARHENIUM(III)

The title compound, Re6Te4Cl10, was obtained by reaction of ReCl5 with elemental Te in an evacuated sealed fused silica tube at 773 K. The s tructure contains two independent Re-6 octahedral clusters, each with a crystallographic center of symmetry. The Re atoms are coordinated by four mu(3)-Te atoms and four mu(3)-Cl ligands that are equally distri buted over the faces of the metal polyhedron. The remaining six Cl ato ms are terminal ligands coordinated to the apices of the Re-6 octahedr on. Distance ranges are: Re-Re 2.618(1)-2.638(1), Re-mu(3)-L 2.530 (3) -2.679 (2), Re-Cl-terminal 2.325 (6)-2.353(5) Angstrom (L is 50% Te an d 50% Cl).
