Heptacarbonyl-1κC,2κC-(4-phenyl-pyridine-1κN)di-μ-phenyltellurido-1:2κTe:Te-dirhenium(I).


ABSTRACT: In the title complex, [Re(2)(C(6)H(5)Te)(2)(C(11)H(9)N)(CO)(7)], two Re atoms are coordinated in slightly distorted octa-hedral coordination environments and are bridged by two Te atoms, which are coordinated in trigonal-pyramidal environments. The torsion angle for the Te-Re-Te-Re sequence of atoms is 17.06 (3)°. The crystal structure is stabilized by weak C-H⋯O and C-H⋯π inter-actions. In addition, there are Te⋯Te distances [4.0392 (12) Å] and O⋯O distances [2.902 (19) Å] which are shorter than the sum of the van der Waals radii for these atoms. A short inter-molecular lone pair⋯π distance [C O⋯Cg = 3.31 (2) Å] is also observed.
