In the centrosymmetric dinuclear title complex, [Cu(2)(C(5)H(6)O(4))(2)(C(12)H(18)N(2))(2)(H(2)O)(2)], the Cu(II) atom displays a dis-torted square-pyramidal coordination environment with the basal plane occupied by two phenanthroline N atoms and two O atoms from different glutarate dianions while a water mol-ecule is located at the apical position. Of the two water H atoms, one is engaged in an intra-molecular hydrogen bond with a free oxygen of the dianion whereas the second is engaged in an inter-molecular hydrogen bond, building a corrugated layer parallel to (100). These layers are further connected through π-π stacking inter-actions involving symmetry-related phenanthroline rings [centroid-centroid distance = 3.5599 (17) and 3.5617 (18) Å], building a three dimensionnal network. C-H⋯π inter-actions involving the phenanthroline ring system are also observed.
在中心对称的双核标题配合物[Cu₂(C₅H₆O₄)₂(C₁₂H₁₈N₂)₂(H₂O)₂]中,Cu(II)原子呈现出扭曲的四方锥配位环境,其基面由两个菲咯啉N原子和来自不同戊二酸二价阴离子的两个O原子占据,而一个水分子位于顶端位置。在两个水分子H原子中,一个与二价阴离子的一个游离氧形成分子内氢键,而另一个参与分子间氢键,形成平行于(100)的波纹层。这些层通过涉及对称相关菲咯啉环的π-π堆积相互作用进一步连接[质心-质心距离 = 3.5599 (17) 和3.5617 (18) Å],构建了一个三维网络。还观察到涉及菲咯啉环系的C-H⋯π相互作用。
