Özet

The title compound,[Cu(C7H5O3)(2)(C6H6N2O)(2)(H2O)(2)], is a two-dimensional hydrogen-bonded supramolecular complex. The Cu-II ion resides on a centre of symmetry and is in an octahedral coordination environment comprising two pyridine N atoms, two carboxylate O atoms and two O atoms from water molecules. Intermolecular N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds produce R-2(2)(4), R-2(2)(8) and R-2(2)(15) rings which lead to one-dimensional polymeric chains. An extensive two-dimensional network of N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds and C-H center dot center dot center dot pi interactions are responsible for crystal stabilization.
