A new polymorph of the title compound, [Pd(2)(C(8)H(18)P)(2)(C(8)H(19)P)(2)], has been found. It belongs to the triclinic P-1 space group, whereas the known form [Leoni, Sommovigo, Pasquali, Sabatino & Braga (1992 ▶), J. Organo-met. Chem.423, 263-270] crystallizes in the monoclinic C2/c space group. The title compound features a dinuclear palladium complex with a planar central Pd(2)(μ-P)(2) core (r.m.s. deviation = 0.003 Å). The Pd-Pd distance of 2.5988 (5) Å is within the range of a Pd(I)-Pd(I) bond. The mol-ecules of both polymorphs are located on a crystallographic centre of inversion. The mol-ecular conformations of the two polymorphs are essentially identical. The crystal packing patterns, on the other hand, are slightly different.
已发现标题化合物[Pd₂(C₈H₁₈P)₂(C₈H₁₉P)₂]的一种新多晶型物。它属于三斜晶系P-1空间群，而已知形式[莱奥尼、索莫维戈、帕斯夸利、萨巴蒂诺和布拉加（1992年▶），《有机金属化学杂志》423，263 - 270]结晶于单斜晶系C2/c空间群。标题化合物具有一个双核钯配合物，其中心Pd₂(μ-P)₂核呈平面状（均方根偏差 = 0.003 Å）。2.5988(5) Å的Pd - Pd距离在Pd(I)-Pd(I)键的范围内。两种多晶型物的分子都位于一个晶体学反演中心上。另一方面，两种多晶型物的分子构象基本相同。然而，晶体堆积模式略有不同。
