| Özet |
| The title compound,[Co (CvHsO3) 2 (C6H6N20) 2 (H20) 2], is a monomeric and centrosymmetric cobalt complex. It contains two 3-hydroxybenzoate anions, two nicotinamide (NA) molecules and two water molecules as ligands. Each ligand is monodentate. The two nearest carboxylate O atoms and the two water O atoms form a slightly distorted square-planar arrangement around the Co atom [with distances of 2.099 (3) and 2.132 (3),~,, respectively], while the distorted octahedral coordination is completed by the pyridine N atoms of the NA ligands at a distance of 2.139 (4) A. There is an intramolecular hydrogen bond between the nicotinamide N and O atoms [N..-O 2.228 (6) A], and the hydroxybenzoate and water O atoms form inter-[2.662 (5) A] and intramolecular [2.586 (5) A] hydrogen bonds, respectively, with the non-coordinated O atom of the carboxylate group. |
