The crystal structures of the title compounds, (CO)3> , have been determined by single-crystal X-ray diffraction methods and refined to residuals of 0.055 and 0.071 for 3.653 and 4 345' observed' reflections respectively.Crystals of (1) are monoclinic, space group P21, with a=20.989(9), b=17.825(10), c=8.784(4) Angstroem, β=99.70(2) deg, and Z=4; those of (2) are monoclinic, space group P21/n, with a=15.181(7), b=18.799(4), c=12.053(4), β=106.62(3) deg, and Z=4.In both (1) and (2), the metal-central phosphorous distance is shorter than the metal-terminal phorous distances .In (1) the mean Cr-C length is 1.84 Angstroem; in (2), the mean Mo-C-length is 1.97 Angstroem.
