The title compound, [Pd(2)(C(13)H(8)N(2)O(2))(C(15)H(11)O(2))(2)], crystallized from a mixture of ethanol and n-hexa-nes. The structure is the first example of β-diketonate in a dianionic κ(2)C-coordination complex containing a Pd(II)-Pd(II) bond. Both Pd(II) atoms adopt a pseudo square-planar coordination geometry. The mol-ecular packing involves π-inter-actions between the phenyl rings of the 1,3-diphenyl-propane-1,3-dionato ligands with centroid-centroid distances in the range 3.823 (2)-3.868 (2) Å.
标题化合物[Pd₂(C₁₃H₈N₂O₂)(C₁₅H₁₁O₂)₂]由乙醇和正己烷的混合物中结晶得到。该结构是含Pd(II)-Pd(II)键的二阴离子κ²C配位络合物中β-二酮酸酯的首个实例。两个Pd(II)原子均采用假平面正方形配位几何构型。分子堆积涉及1,3-二苯基丙烷-1,3-二酮酸酯配体苯环之间的π相互作用，质心间距在3.823(2)-3.868(2) Å范围内。
