Abstract

In the asymmetric unit of the title compound, [Cu(C8H3NO6)(C10H8N2)(H2O)]n, there are two symmetry-independent one-dimensional coordination polymers related by a non-crystallographic inversion center. Within the polymers, the CuII atoms, coordinated by the water mol­ecule and the chelating 2,2′-bipyridine ligands, are bridged by 5-nitro­benzene-1,3-dicarboxyl­ate dianions which act as tridentate ligands; the carboxyl­ate groups exhibit monodentate and symmetric bidentate coordination modes. The CuII atoms show a strongly distorted octa­hedral coordination geometry. In the crystal structure, the two symmetry-independent coordination polymers form another one-dimensional polymeric structure via O—H⋯O hydrogen bonds between coordinated water mol­ecules and carboxyl­ate groups.

Highlights

  • After further thorough investigation, articles are retracted as a result of problems with the data sets or incorrect atom assignments

Summary

This article reports the retraction of articles published in Acta

Crystallographica Section E between 2007 and 2009. After further thorough investigation (see Harrison et al., 2010), articles are retracted as a result of problems with the data sets or incorrect atom assignments. Details of articles to be retracted, in order of publication. Tetraaquabis(4,40 -bipyridine)cobalt(II) pyridine-2,6-dicarboxylate tetrahydrate cyclo-Tetrakis[-N-(2-hydroxybenzoyl)-N0 -(2-hydroxy-3-methoxybenzylidene)hydrazinato(2)]tetranickel(II) N,N-dimethylformamide tetrasolvate.
