Abstract
The dinuclear mol-ecule of the title compound, [Mo(2)(C(9)H(13))(2)(CO)(6)] or [Mo( (t) BuCp)(CO)(3)](2) where (t) Bu and Cp are tert-butyl and cyclo-penta-dienyl, is centrosymmetric and is characterized by an Mo-Mo bond length of 3.2323 (3) Å. Imposed by inversion symmetry, the (t) BuCp and the carbonyl ligands are in a transoid arrangement to each other. In the crystal, inter-molecular C-H⋯O contacts lead to the formation of layers parallel to the bc plane.
