In the title centrosymmetric binuclear Cu(II) complex, [Cu(2)(C(8)H(7)O(2))(4)(C(9)H(7)N)(2)], the two Cu cations are bridged by four carboxyl-ate groups of the phenyl-acetate anions; each Cu cation is further coordinated by an isoquinoline ligand to complete the distorted CuO(4)N square-pyramidal geometry. The Cu cation is displaced by 0.2092 (8) Å from the basal plane formed by the four O atoms. Within the dinuclear mol-ecule, the Cu⋯Cu separation is 2.6453 (6) Å. Although a parallel, overlapped arrangement of isoquinoline ligands exists in the crystal structure; the longer face-to-face distance of 3.667 (5) Å suggests there is no π-π stacking between isoquinoline ring systems.
在标题为中心对称双核铜（II）配合物[Cu₂(C₈H₇O₂)₄(C₉H₇N)₂]中，两个铜阳离子由四个苯乙酸根阴离子的羧酸根基团桥连；每个铜阳离子进一步与一个异喹啉配体配位，以形成扭曲的CuO₄N四方锥几何构型。铜阳离子从由四个O原子形成的基面偏移0.2092(8) Å。在双核分子中，Cu⋯Cu间距为2.6453(6) Å。尽管在晶体结构中存在异喹啉配体的平行、重叠排列；但3.667(5) Å的较长面对面距离表明异喹啉环系统之间不存在π-π堆积。
