In the title complex, [PdI(2)(C(8)H(6)N(4))], the Pd(II) ion is four-coordinated in a slightly distorted square-planar environment defined by two pyrimidine N atoms derived from a chelating 2,2'-bipyrimidine (bpym) ligand and two mutually cis iodide anions. The nearly planar bpym ligand [maximum deviation = 0.053 (3) Å] is slightly inclined to the least-squares plane of the PdI(2)N(2) unit [maximum deviation = 0.055 (2) Å], making a dihedral angle of 3.9 (2)°. In the crystal, pairs of complex mol-ecules are assembled by inter-molecular C-H⋯N hydrogen bonds into dimers. Intra-molecular C-H⋯I hydrogen bonds are also observed.
在标题配合物[PdI₂(C₈H₆N₄)]中，Pd(II)离子在由螯合的2,2'-联嘧啶（bpym）配体衍生的两个嘧啶N原子和两个相互顺式的碘阴离子所定义的略微扭曲的平面正方形环境中呈四配位。近乎平面的bpym配体[最大偏差 = 0.053 (3) Å]相对于PdI₂N₂单元的最小二乘平面略微倾斜[最大偏差 = 0.055 (2) Å]，二面角为3.9 (2)°。在晶体中，配合物分子对通过分子间C—H⋯N氢键组装成二聚体。还观察到分子内C—H⋯I氢键。
