Tetra-μ2-acetato-κ8O:O′-bis[(isoquinoline-κN)copper(II)]

In the crystal structure of the title compound, [Cu-2(CH3-COO)(4)(C9H7N)(2)], the Cu-II cation is coordinated by four acetate anions and one isoquinoline molecule in a distorted square-pyramidal geometry; the Cu-II cation is 0.1681 (6) angstrom 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 molecule, the Cu center dot center dot center dot Cu separation is 2.6459 (4) angstrom. A parallel arrangement of isoquinoline ligands of adjacent complexes is observed in the crystal structure; the face-to-face distance of 3.610 (10) angstrom suggests there is no pi-pi stacking between isoquinoline ring systems.
