Diaqua­(Isonicotinamide-Κn 1)(4-Meth­Oxy­Benzoato-Κ2 O,O′)(4-Meth­Oxy­Benzoato-Κo)Cobalt(Ii)

Abstract

In the title complex, [Co(C8H7O3)2(C6H6N2O)(H2O)2], the CoII atom is coordinated by three O atoms from two 4-meth­oxy­benzoate ligands, which act in different modes, viz. monodentate and bidentate, two water mol­ecules and one N atom of the isonicotinamide ligand in a distorted octa­hedral geometry. The monodentate-coordinated carboxyl­ate group is involved in an intra­molecular O—H⋯O hydrogen bond with the coordinated water mol­ecule. In the crystal structure, inter­molecular O—H⋯O and N—H⋯O hydrogen bonds link the mol­ecules into layers parallel to the ab plane. The crystal packing is further stabilized by weak C—H⋯O hydrogen bonds and π–π inter­actions indicated by the short distance of 3.6181 (8) Å between the centroids of the benzene and pyridine rings of neighbouring mol­ecules.
