Co2 ( CO ) 6 (dppp ) Cdppp = 1,3-bis ( diphenylphosphino ) propane = Ph2P(CH2)3PPh2D, Mr=698. 38, monoclinic, space group P21/c, a=14. 952(8) , b = 13.44(2), c = 16. 72(1) A. β=110.56(4)°, V=3147(9) A3, Z = 4, A=1. 47 g/cm3, λ(MoXα) = 0. 71069 A, F(000) = 1424, λ(MoKα) = 11. 93 cm-1, R = 0. 032 and Rw = 0. 044 for 4553 observed independent reflections with I>4. 0σ(I). The molecular structure of the complex shows that the dppp ligand chelates one of the two cobalt atoms of the complex molecule, and there are two bridging carbonyl groups between the two cobalt atoms. The Co-Co bond length is 2. 534(3) A . The chelating dppp ligand results in the asymmetrization of the molecule.
