Abstract

In the title compound, [Cu(C14H8O5)(C12H12N2)(H2O)]n, the CuII ion is penta­coordinated in a square-pyramidal geometry. Two N atoms of the chelating 5,5′-dimethyl-2,2′-bipyridine (dbp) ligand and two O atoms of two different 2,2′-oxydibenzoic (odb) ligands occupy the basal plane while the water O atom completes the square-pyramidal geometry at the apical site. The non-water N2O2 donor atoms are nearly coplanar, with a mean deviation from the least-squares plane of 0.0518 (11) Å and the Cu atom is displaced by 0.1507 (11) Å from this plane towards the apical water O atom. Further coordination via the 2,2′-oxydibenzoate anions forms a one-dimensional coordination polymer extending parallel to [010]. In the crystal structure, O—H⋯O hydrogen bonds link the mol­ecules into a two-dimensional supra­molecular structure.

Nitrosalicylatocopper(II) complexes with chelating pyridine derivatives

“…al., 2009) or hydroxide-imine (2-hmpy) groups (Yilmaz et al, 2002). Salicylate anions offer a wider range of bonding modes from the most common monodentate (Icbudak et al, 2003;Devereuxe et al, 2007;Repická et al, 2012;Mirzaei et al, 2012), through bidentate-chelating (Mirzaei et al, 2012;Gembicky et al, 2008) and bridging (Mei et al, 2010), to chelating-bridging (Mukherjee et al, 2012;Palanisami et al, 2006). This paper is focused on the preparation and spectral properties of 5-nitrosalicylatocopper(II) and 3,5-dinitrosalicylatocopper(II) complexes with 2-(aminomethyl)pyridine and/or 2-(hydroxymethyl) pyridine.…”
