合成了双氯桥双核钯配合物［Ｐｈ_２Ｐ（ｏ－Ｃ_６Ｈ_４ＣＯ）ＰｄＣｌ］_２·２ＣＨ_２Ｃｌ_２进行了元素分析、红外光谱表征和晶体结构测定，研究了其催化氢化性能。在３０～８０℃、氢分压１．０～５．０ＭＰａ的范围内。发现该配合物是催化氢化丙烯酸为丙酸的有效催化剂．晶体［Ｐｄ_２Ｃｌ_２（Ｃ_（１９）Ｈ_（１４）ＯＰ）_２］·２ＣＨ_２Ｃｌ_２属Ｐ１空间群，ａ＝０．９３０４（３）ｎｍ，ｂ＝１．０３９２（２）ｎｍ，ｃ＝１．１０６２（３）ｎｍ；ａ＝１０２．７８（２），Ｂ＝９７．３５（３），γ＝９５．２５（２），Ｖ＝１．０２６４ｎｍ~３，Ｍ＝１０３２．１７，２＝１，Ｄｃ＝１．６７０ｇ／ｃｍ~３，ｕ＝１３．６９５ｃｍ^（－１），Ｆ（０００）＝５１２，用１９４５个独立衍射精修结构，最终Ｒ＝０．０３６。

共平面的μ-S桥联(1,10-菲咯啉)钯(Ⅱ)双核配合物的晶体结构与π-π堆积(英文)

A novel μ-S-bridged di-palladium(Ⅱ) complex, {[(phen)Pd( μ-SPr)2Pd(phen)](NO3)2·2H2O} (1) was synthesized and characterized by the 1H NMR, element analysis and single crystal X-ray diffraction. It crystallizes in the monoclinic space group C2/c with unit cell parameters: a=2.165 1(3) nm, b=1.291 4(2) nm, c=2.716 2(3) nm, β=111.987(3)°, and V=7.041 8(16) nm3, Z=8, R=0.054 4, wR=0.127 4. The X-ray crystal structure analysis revealed that two 1,10-phenanthroline palladium(Ⅱ) moieties were bridged by two n-propylmercapatan molecules in coplanar fashion with the dimensions of 1.55 nm × 0.88 nm. The plane-to-plane distance of the complex 1 is 0.33 nm, which reveals strong aromatic-aromatic π-π interaction. CCDC: 292998.
