title: Tetra-μ-acetato-bis-{[9-(pyrazin-2-yl)-9H-carbazole]copper(II)}.
abstract: The title complex, [Cu(2)(CH(3)COO)(4)(C(16)H(11)N(3))(2)], lies on an inversion centre, with four acetate ligands bridging two symmetry-related Cu(II) ions and two monodentate 9-(pyrazin-2-yl)-9H-carbazole ligands coordinating each Cu(II) ion via the N atoms of the pyrazine rings, forming slightly distorted square-pyramidal geometries. There are weak π-π stacking inter-actions between the pyrrole rings of symmetry-related mol-ecules, with a centroid-to-centroid distance of 3.692 (2) Å.
