{[Co(pht)(bpy)(H2O)].3(H2O)}n (where pht is phthalato and bpy is 4,4´-bipyridine ) is the Co isologue of its Ni counterpart, reported by Yang et al., (2003). Acta Cryst. E59, m507?m509. The compound presents the cobalt(II) cation octahedrally coordinated by 2 N´s provided by two bpy, three oxygens coming from phthalate anions and the fourth one, from a coordinated water molecule. The packing consists of broad planes linked by H-bonds mediated by the three hydration water molecules; the linkage is achieved by the water solvates forming intricate oligomeric clusters which also involve O atoms from the MOF.
