Poly[tris-(µ(3)-5-amino-isophthalato)diaqua-dicerium(III)].

ABSTRACT

In the title complex, [Ce(2)(C(8)H(5)NO(4))(3)(H(2)O)(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 mol-ecule. Both carboxyl-ate groups from the ligands chelate the Ce atoms, forming two four-membered rings. The 5-amino-isophthalate ligands also bridge the Ce centers, forming a two-dimensional network, and O-H⋯O and N-H⋯O hydrogen bonds complete the structure.
