Notes:
In the present redetermination of the complex cis-tetracarbonylbis(tricyclohexylphosphine)molybdenum(0), (I), [Mo(C18H33P)2(CO)4] or cis-{η1-[P(C6H11)3]2}Mo(CO)4, the Mo atom has a distorted octahedral geometry with a large P—Mo—P angle of 104.8 (1)°. A strong trans influence on the carbonyls in (I) is seen in a shortening of the Mo—C and a lengthening of the C—O distances opposite the phosphines compared with those that are cis. This influence is greatly diminished in the complex pentacarbonyl(tricyclohexylphosphine)molybdenum(0), (II), [Mo(C18H33P)(CO)5] or {η1-[P(C6H11)3]}Mo(CO)5, the core of which has a slightly distorted C4v geometry.
