In the title mol-ecule, C(8)H(8)Cl(2)N(4), the essentially planar imidazole and pyrimidine rings [maximum deviations of 0.0030 (15) and 0.0111 (15) Å, respectively] make a dihedral angle of 1.32 (8)°. In the crystal, the fused-ring systems are stacked approximately parallel to the bc plane, with a centroid-centroid distance between inversion-related pyrimidine rings of 3.5189 (9) Å.
在标题分子C₈H₈Cl₂N₄中,基本呈平面状的咪唑环和嘧啶环[最大偏差分别为0.0030 (15) Å和0.0111 (15) Å]形成的二面角为1.32 (8)°。在晶体中,稠环体系大致平行于bc平面堆叠,反演相关嘧啶环之间的质心间距为3.5189 (9) Å。
