Abstract: In the title compound, [Co(C₈H₅NO₄)(H₂O)₂]_n, the Co^II atom is coordinated in a distorted octahedral fashion by three O atoms of two carboxylate groups (one in a monodentate and one in a 1,3-bidentate mode) from two 5-aminoisophthalate anions, one N atom from the third 5-aminoisophthalate anion and two aqua ligands. The complex consists of an infinite neutral railroad-like linear polymer, which is packed into a three-dimensional framework through intricate N-HO and O-HO hydrogen bonding.
