In the mononuclear title complex, [Co(C(9)H(9)O(3))(2)(H(2)O)(2)], each Co(II) atom is located on an inversion center and is hexa-coordinated by four O atoms from two benzyl-oxyacetate ligands [Co-O bond lengths = 2.0487 (9) and 2.1090 (9) Å] and two water mol-ecules [Co-O bond length = 2.0873 (9) Å] in a distorted octa-hedral geometry. In the crystal structure, inter-molecular hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance between phenyl rings = 3.692 (2) Å] link the mol-ecules into a supra-molecular structure.
