Deskripsi

The title compound, [Re2(C6H5Te)2(CO)8], crystallizes with two molecules in the asymmetric unit, in which two Re atoms are coordinated in a slightly distorted octahedral 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 molecules. Thus, the Re—Te four-membered rings in the two molecules deviate significantly from planarity. Two intramolecular C—H...O interactions occur in one of the molecules. Te—Te [4.0551 (10) Å] interactions between the two molecules and weak intermolecular C—H...O interactions stabilize the crystal packing.
