چکیده
In the title compound, [Cu(C12H16NO2)2], the Cu(II) ion, located on a center of inversion, is coordinated by two singly deprotonated Schiff base ligands derived from condensation of salicyldehyde and 1-amino-pentan-5-ol. The imino N and phenol O atoms from both ligands offer a square-planar arrangement around the metal ion. The Cu-N and Cu-O bond lengths are 2.0146 (15) and 1.8870 (12) Å, respectively. Since the Cu-O and Cu-N bond lengths are different, it can be concluded that the resulting geometry of the complex is distorted. The aliphatic -OH group of the ligand is not coordinated and points away from the metal coordination zone and actively participates in hydrogen bonding connecting two other units and thus stabilizing the crystal lattice. This results in a two-dimensional extended array parallel to (201).

Redetermination of bis(2-formylphenolato-κ2 O,O′)nickel(II) as bis[2-(iminomethyl)phenolato-κ2 N,O′]nickel(II)
The crystal structure of bis-(2-formyl-phenolato-κ(2)O,O')nickel(II), [Ni(C(7)H(5)O(2))(2)], a square-planar centrosymmetric complex, has been reported previously [Li & Chen (2006). Acta Cryst. E62, m1038-m1039]. However, a number of warning signs allows the assumption that the carbonyl group in the salicylaldehydate ligand of the claimed complex is incorrect. The crystal structure was therefor...

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-base...
