Poly[diaquatris(μ4-1,3-phenylene-diacetato)dicerium(III)]

Abstract

In the title coordination polymer, [Ce2(C10H 8O4)3(H2O)2] n, each CeIII atom is nine-coordinated by eight O atoms from six different 1,3-phenylenediacetate (pda) bivalent anions and one O atom from a coordinated water molecule, forming a distorted tricapped trigonal-prismatic coordination geometry. Eight CeIII ions and twelve pda ligands form a large [Ce8(pda)12] ring, and four CeIII ions and six pda ligands form a small [Ce4(pda) 6] ring. The rings are further connected by the coordination interactions of pda ligands and CeIII, generating a three-dimensional supramolecular framework.
