In the title compound, poly[[aqua(1,10‐phenanthroline)­cobalt(II)]‐μ4‐di­hydrogen benzene‐1,2,4,5‐tetra­carboxyl­ato], [Co(C10H4O8)(C12H8N2)(H2O)]n, each cobalt(II) cation has an octahedral geometry completed by one aqua O atom, three carboxy O atoms belonging to three H2TCB2− anions (H2TCB2− is di­hydrogen ­benzene‐1,2,4,5‐tetra­carboxyl­ate) and two N atoms from a 1,10‐phenanthroline mol­ecule. In the asymmetric unit, there are two half H2TCB2− anions lying about independent inversion centres. The bridging H2TCB2− anions have two coordination modes, viz.μ2‐H2TCB2− and μ4‐H2TCB2−, resulting in a two‐dimensional coordination polymer. Furthermore, a three‐dimensional network is formed by Ocarboxy⋯Ocarboxy hydrogen‐bond interactions, with H⋯A distances in the range 1.69–1.82 Å, and Ocarboxy⋯Owater interactions, with H⋯A distances in the range 1.91–1.94 Å.
