The central CuN(4)O(2) motif of the title compound, Cu(ClO(4))(2)(C(8)H(6)N(4))(C(10)H(8)N(2)), exhibits a Jahn-Teller-distorted octa-hedral geometry around the metal centre, showing a considerably long Cu-O bond distance of 2.634 (4) Å towards the second perchlorate group occupying the sixth coordination site, giving a (4+1+1)-type coordination mode. The 4,4'-bipyridine (bipy) ligands are highly twisted with respect to each other, the dihedral angle between the two pyridyl ring planes being 38.9 (2)°. The bipy ligands act as bridging ligands between [Cu(ClO(4))(2)(2,2'-bpym)] (2,2'-bpym is 2,2'-bipyrimidine) units, generating an infinite one-dimensional zigzag chain along [010]. Intra- and intermolecular C-H⋯O hydrogen bonds are present in the crystal structure.
标题化合物[Cu(ClO₄)₂(C₈H₆N₄)(C₁₀H₈N₂)]ₙ的中心CuN(4)O(2) motif在金属中心周围呈现出Jahn-Teller畸变的八面体几何构型，朝着占据第六配位位点的第二个高氯酸根基团显示出相当长的Cu - O键距，为2.634 (4) Å，呈现出(4 + 1 + 1)型配位模式。4,4'-联吡啶（bipy）配体相互之间高度扭曲，两个吡啶环平面之间的二面角为38.9 (2)°。bipy配体充当[Cu(ClO₄)₂(2,2'-bpym)]（2,2'-bpym为2,2'-联嘧啶）单元之间的桥连配体，沿着[010]生成无限的一维锯齿链。晶体结构中存在分子内和分子间的C - H⋯O氢键。
