Tetra-μ(2)-acetato-κO:O'-bis-[(isoquinoline-κN)copper(II)].

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.
