trans-Diaquabis(nicotinamide-kappaN)bis(salicylato-kappaO)cobalt(II).
The title compound, [Co(C(7)H(5)O(3))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], forms a three-dimensional hydrogen-bonded supramolecular structure. The Co(II) ion is in an octahedral coordination environment comprising two pyridyl N atoms, two carboxylate O atoms and two O atoms from water molecules. Intermolecular N-H...O and O-H...O hydrogen bonds produce R(2)(2)(8), R(2)(2)(12) and R(2)(2)(14) rings, which lead to two-dimensional chains. An extensive three-dimensional supramolecular network of C-H...O, N-H...O and O-H...O hydrogen bonds and C-H...pi interactions is responsible for crystal structure stabilization. This study is an example of the construction of a supramolecular assembly based on hydrogen bonds in mixed-ligand metal complexes.
