Diaqua­Bis(N,N-Diethyl­Nicotinamide-Κn1)Bis­(4-Formyl­Benzoato-Κo)Cobalt(Ii)

Abstract

In the crystal structure of the title CoII complex, [Co(C8H5O3)2(C10H14N2O)2(H2O)2], the metal centre is located on an inversion center and is coordinated by two 4-formyl­benzoate (FOB), two diethyl­nicotinamide (DENA) ligands and two water mol­ecules in a slightly distorted CoO4N2 octa­hedral geometry. In the crystal structure, O—H⋯O hydrogen bonds link the mol­ecules into infinite chains. π–π contacts between the parallel pyridine rings of neighboring DENA ligands [centroid–centroid distance = 3.652 (3) Å] further stabilize the crystal structure.
