Bis[3-(4-carboxyphenoxy)propionato-κO]bis[3-(4-carboxyphenoxy)propionic acid-κO]bis(pyridine-κN)cobalt(II)

Abstract

The title complex, [Co(C10H9O5)2(C10H10O5)2(C5H5N)2], is a neutral mononuclear complex. The CoII atom, which lies on a centre of symmetry, has a distorted octa­hedral geometry involving two O atoms of the 3-(4-carboxy­phen­oxy)propionate groups, two O atoms of the 3-(4-carboxy­phen­oxy)propionic acid groups and two N atoms of two pyridine ligands. A two-dimensional supra­molecular structure is constructed via π–π inter­actions [centroid-to-centroid distance 3.589 (3) Å] and hydrogen-bonding inter­actions.
