In the crystal structure of the title compound, [Cu(2)(CH(3)COO)(4)(C(9)H(7)N)(2)], the Cu(II) cation is coordinated by four acetate anions and one isoquinoline mol-ecule in a distorted square-pyramidal geometry; the Cu(II) cation is 0.1681 (6) Å from the basal coordination plane formed by the four O atoms. Each acetate anion bridges two Cu(II) cations to form the centrosymmetric dinuclear complex. Within the dinuclear mol-ecule, the Cu⋯Cu separation is 2.6459 (4) Å. A parallel arrangement of isoquinoline ligands of adjacent complexes is observed in the crystal structure; the face-to-face distance of 3.610 (10) Å suggests there is no π-π stacking between isoquinoline ring systems.
在标题化合物[Cu₂(CH₃COO)₄(C₉H₇N)₂]的晶体结构中，Cu(II)阳离子由四个醋酸根阴离子和一个异喹啉分子以扭曲的四方锥几何构型配位；Cu(II)阳离子距离由四个O原子形成的基面配位平面0.1681(6) Å。每个醋酸根阴离子桥连两个Cu(II)阳离子形成中心对称的双核配合物。在双核分子中，Cu⋯Cu间距为2.6459(4) Å。在晶体结构中观察到相邻配合物的异喹啉配体呈平行排列；面对面距离为3.610(10) Å，表明异喹啉环系统之间不存在π-π堆积。
