• The crystal structure of bis(pyridine-2-acetamide)copper(II) perchlorate, Cu(paaH)<SUB>2</SUB>(ClO<SUB>4</SUB>)<SUB>2</SUB>, was determined from three-dimensional X-ray photographic data and refined by block-diagonal least-squares methods, using 1698 independent reflections to give <I>R</I>=0.12. The crystals are monoclinic with a space group of C2/c. There are four formula units in a unit cell with dimensions of: <I>a</I>=10.957, <I>b</I>=12.178, <I>c</I>=15.566 Å, and β=108.7°. The complex is centrosymmetric and square-planar, with two ligand molecules coordinating to the copper atom in <I>trans</I> positions through the amide-oxygen and the ring-nitrogen atoms. Two perchlorate ions coordinate weakly to the central copper atom through one of the four oxygen atoms from the top and bottom of the plane containing copper, amide-oxygen, and ring-nitrogen atoms.
