摘　　要：The crystal and molecular structure of(u-C2H5S)[μ-CO-C(CH3)-CH2]Fe2(CO)6, Mr = 409.958 has been determined by X-ray diffraction method. Crystals of this complex are monoclinic, belonging to space group P21/c, and the cell parameters are a = 9.191(1), b = 9.666(1), c = 18.47(2)A,β=98.71(1)° V= 1621.9A3,Z=4,Dc=1.68g/cm3.Thg final R and Rw equal 0.058 and 0.089 for 1948 observed unique reflections. The acyl and ethyl-thio groups are bridged to two iron atoms to form an envelope type of structure. The bond lengths of Fe(1)-0(1), Fe(2)-C(1), Fe(l)-S, Fe(2)-S, Fe(l)-Fe(2) involved in the envelope structure are 1.992, 1.980, 2.260, 2.242 and 2.552A, respectively.The crystal and molecular structure of(u-C2H5S)[μ-CO-C(CH3)-CH2]Fe2(CO)6, Mr = 409.958 has been determined by X-ray diffraction method.
