The reaction of Et4NCl, C6H5SeNa and W(CO)6 in MeCN afforded a new dinuclear tungsten(Ⅰ) complex W2(SePh)2(CO)6(MeCN)2 1 (Mr = 929.98). The crystal structure has been determined by X-ray single-crystal diffraction. 1 Crystallizes in monoclinic, space group P21/n with a = 7.501(1), b = 18.387(2), c = 9.491(1) (A), β = 103.897(2)°, V = 1270.6(3) (A)3, Z = 2, Dc = 2.431g/cm3, μ = 119.50 cm-1, F(000) = 852, R = 0.0695 and wR = 0.1724 for 2220 independent reflections with I ＞ 2σ(Ⅰ). The X-ray structure analysis reveals that the W2Se2 core of 1 is planar with W-W bond length of 3.0433(13) (A) and W-Se of 2.5922(17) (A).
