Abstract: In the title complex, [Ce₂(C₈H₅NO₄)₃(H₂O)₂]_n, each Ce ion is in nine-coordinated environment. Eight O atoms from six ligands participate in coordination, in addition to one O atom from a water molecule. Both carboxylate groups from the ligands chelate the Ce atoms, forming two four-membered rings. The 5-aminoisophthalate ligands also bridge the Ce centers, forming a two-dimensional network, and O-HO and N-HO hydrogen bonds complete the structure.
