Bis(?-phenyl-tellurido-?Te:Te)bis-[tetra-carbonyl-rhenium(I)].

ABSTRACT: The title compound, [Re(2)(C(6)H(5)Te)(2)(CO)(8)], crystallizes with two mol-ecules in the asymmetric unit, in which two Re atoms are coordinated in a slightly distorted octa-hedral environment and are bridged by two Te atoms, which show a distorted trigonal-pyramidal geometry. The torsion angles for the Te-Re-Te-Re sequence of atoms are 19.29?(18) and 16.54?(16)° in the two mol-ecules. Thus, the Re-Te four-membered rings in the two mol-ecules deviate significantly from planarity. Two intra-molecular C-H?O inter-actions occur in one of the mol-ecules. Te-Te [4.0551?(10)?Å] inter-actions between the two mol-ecules and weak inter-molecular C-H?O inter-actions stabilize the crystal packing.
