In the title compounds, [Cr(C21H21O3P)(CO)(5)] and [Mo(C-21 H21O3P)(CO
)(5)], the M-C bend lengths for the cis-carbonyl ligands (with respect
to the phosphine) are longer than that observed for the trans-carbony
l group. The chromium compound has short intermolecular O ... O contac
ts, The two crystal structures are not isomorphous and crystallize in
triclinic and monoclinic systems, respectively.
