At room temperature, the double butterfly complex <<(CO)6Fe2(μ-Se)2>2(C(Ph)-C(H)> reacted with Pt(C2H4)(PPh3)2 to give <(CO)6Fe2(μ-SeC(Ph)C(H)Se)>, <(CO)6Fe2Pt(PPh3)2<μ-SeC(Ph)C(H)Se>> and <(CO)6Fe2(μ3-Se)2Pt(PPh3)2>.It reacted with dppe to form the substituted derivative <<(CO)5Fe2(μ-Se)2>2C(Ph)C(H)(μ-dppe)>, which was subjected to an X-ray diffraction analysis.The crystal of <<(CO)5Fe2(μ-Se)2>2C(Ph)C(H)(μ-dppe)> is triclinic with the space group P<*>, a=12.969(1), b=13.032(1), c=18.669(1) Angstroem, α=76.81(1), β=72.74(1), γ=63.99(1)^o, Z=2.The structure was refined by the block-matrix least squares method.The final R and R_w values were 0.0435 and 0.0492 respectively.Key words: Iron; Selenium; X-ray diffraction
