Crystal of [Et4N][Mo(CO)5I](1) (Mr = 493. 15) is tetragonal with space group P4/n, a =b==9. 374(2) ,c=10. 545(2)(?), V=926. 5(?)3, Z = 2, F(000) = 480, Dc=1. 77g/cm3and μ = 23. 6cm-1. R = 0. 040, Rw = 0.043 for 374 observed reflections. Crystal of [Et4N][Mb(CO)5(SPh)] (2) is orthorhombic ith space group Pbam, a= 15. 230(3), b = 18. 389(10), c=8. 172(3)(?), V=2288. 6 (?)3, Z = 4, Dc=1. 38gcm3, μ = 6.7cm-1.R = 0. 043, Rw = 0. 042 for 1621 observed reflections. Complexes 1 and 2 possess the same geometry. The Mo atom is octahe-drally coordinated with obvious trans drrdct, all the Mo -C bond lengths are shorter obviously and the C - O bond are longer than those of Mo(CO)6.
