title: Bis{μ-2-[(pyridin-2-yl)imino-meth-yl]phenolato}bis-[(2-formyl-phenolato)copper(II)].
abstract: The asymmetric unit of the title compound, [Cu(2)(C(12)H(9)N(2)O)(2)(C(7)H(5)O(2))(2)], contains two independent (2-formyl-phen-olato){2-[(pyridin-2-yl)imino-meth-yl]phenolato}copper(II) mol-ecules that form pseudocentrosymmetric dimers via inter-actions between the Cu and pyridyl N atoms of independent monomers. The square-planar geometry of the Cu atoms in the monomer thus becomes square-based pyramidal in the dimer. The crystal studied was an inversion twin, with unequal populations of 0.353 (17) and 0.647 (17).
