A new anionic dinuclear ruthenium complex bearing 1, 2‐his(diphenylphosphinomethyl)benzene (BDPX) [NH 2 Et 2 ][{RuCl (BDPX)} 2 (μ‐Cl) 3 ] (1) was synthesized and its structure was determined by an X‐ray crystallo‐graphic analysis. This result indicated that complex 1 consisted of an anion dinuclear BDPX‐Ru and a cationic di‐ethylammonium. The crystal belonged to monoclinic system, C2/c space group with a =3.3552(7) nm, b= 1.8448(4) nm, c =2.4265(5) nm, β= 101.89(3)° and Z=8. The catalytic hydrogenation activities and selectivities of complex 1 for cinnamaldehyde were investigated.
