Two binuclear ruthenium vinyl complexes with dithienylethene unit [RuCl（CO）（PMe3）3]2（μ-2,2′-（CH=CH）2-DTE）（1a） and [RuCl（CO）（PMe3）3]2（μ-2,5-（CH=CH）2-DTE）（1b） have been synthesized and characterized by elemental analysis,IR spectra, NMR spectra and electrochemical property. Single crystal X-ray diffraction analysis showed that complex 1a crystallized in Monoclinic, space group C2/c with a=3.445 75（6） nm, b=1.459 45（2） nm,c=2.321 91（5） nm, β=110.977 0（10）°, V=10.902 8（3） nm3, Z=8, Dc=1.467 g·cm-3, λ=0.071 073 nm, μ（Mo Kα）=0.956 mm-1and F（000）=4 912. The UV-Vis absorption spectral changes of the two complexes were measured upon UV and visible light, and their photochromic properties were also discussed. CCDC： 1003551, 1a.
