The Mo atom in tricarbonyl(eta6-trimethylphenylsilane)molybdenum, [Mo(
C9H14Si)(CO)3] (1), is situated 1.908 (3) angstrom above the centre of
the arene ring with Mo-C distances in the range 2.351 (5)-2.388 (5) a
ngstrom. The carbonyl groups are staggered (26-degrees from a fully ec
lipsed conformation) with respect to the arene-ring C atoms.
