Diaquabis(N,N-diethylnicotinamide-N1)bis(2-hydroxybenzoato-O)cobalt(II)

The title monomeric centrosymmetric cobalt complex, [Co(C7H5O3)2(C10H14N2O)2(H2O)2], contains two water molecules, two 4-hydroxybenzoate ligands and two diethylnicotinamide (DENA) ligands. All ligands are coordinated to the Co atom as monodentate ligands. The four nearest O atoms around the Co atom form a slightly distorted square-planar arrangement with the distorted octahedral coordination completed by the pyridine N atoms of the DENA ligand at a distance of 2.141 (5) Å. The water molecules are hydrogen bonded to the carboxyl O atoms [O⋯O 2.687 (5) Å].
