Synthesis and crystal structure of a new coordination polymer based on lanthanum and 1,4-phenyl-enedi-acetate ligands.

ABSTRACT: Reaction in gel between the sodium salt of 1,4-phenyl-enedi-acetic acid (Na₂C₁₀O₄H₈-Na₂ p-pda) and lanthanum chloride yields single crystals of the three-dimensional coordination polymer poly[[tetra-aqua-tris-(μ-1,4-phenyl-enedi-acetato)-dilanthanum(III)] octa-hydrate], {[La₂(C₁₀H₈O₄)₃(H₂O)₄]·8H₂O}_∞. The La^III coordination polyhedron can be described as a slightly distorted monocapped square anti-prism. One of the two p-pda^2- ligands is bound to four La^III ions and the other to two La^III ions. Each La^III atom is coordinated by five ligands, thereby generating a metal-org
