In the mononuclear title complex, [Co(C 9H 9O 3) 2(H 2O) 2], each Co II atom is located on an inversion center and is hexacoordinated by four O atoms from two benzyloxyacetate ligands [Co—O bond lengths = 2.0487 (9) and 2.1090 (9) Å] and two water molecules [Co—O bond length = 2.0873 (9) Å] in a distorted octahedral geometry. In the crystal structure, intermolecular hydrogen bonds and π–π stacking interactions [centroid–centroid distance between phenyl rings = 3.692 (2) Å] link the molecules into a supramolecular structure.
