The elemental analysis, IR characterization and crystal structure determination of [D 2 P (o-C 6 H 4 CO) PdCl] 2 · 2CH 2 Cl 2 have been synthesized and the catalytic hydrogenation performance has been studied. The hydrogen partial pressure is in the range of 1.0 to 5.0 MPa at 30 to 80 ° C. The complex was found to be an effective catalyst for the catalytic hydrogenation of acrylic acid to propionic acid. The crystal space of [Pd_2Cl_2 (C_ (19) H_ (14) OP) _2] · 2CH_2Cl_2 is P1 space group, a = 0.9304 (3) nm, b = 1.0392 ) Nm; a = 102.78 (2), B = 97.35 (3), γ = 95.25 (2), V = 1.0264 nm ~ 3, M = 1032.17, 2 = 1, Dc = 1.670g / cm ~ 3, u = 13.695cm ~ (-1) and F (000) = 512. The structure was refined with 1945 independent diffraction and the final R = 0.036.
