摘要

The two title compounds C sub 6 H sub 5 PCo sub 3 (CO) sub 9 and C sub 6 H sub 5 PFeCo sub 2 (CO) sub 9 differ only in the replacement of one cobalt atom by iron. The paramagnetic C sub 6 H sub 5 PCo sub 3 (CO) sub 9 crystallizes in the monoclinic system. Diamagnetic C sub 6 H sub 5 PFeCo sub 2 (CO) sub 9 is monoclinic. Both structures have been determined using Patterson and Fourier methods and refined to R values of 0.071 (CO sub 3 compound) and 0.058 (FeCo sub 2 compound) for 2841 and 2566 reflections, respectively. The shapes of both molecules are nearly identical, but the additional antibonding electron lengthens the metal/endash/metal bonds in the CO sub 3 compound to 2.717 (2) /angstrom/ (av.) as compared to 2.623 (2) /angstrom/ (av.) in the FeCo sub 2 compound. Slight differences in the molecular packing of both compounds cause grossly different sizes and symmetries of their unit cells. 12 refs., 4 figs., 3 tabs. (ERA citation 14:017943)
