Poly[diaqua-tris(μ4-isophthalato)dilanthanum(III)]

Abstract

In the title coordination polymer, [La2(C8H 4O4)3(H2O)2] n , there are two independent LaIII atoms which are coordinated differently in slightly distorted penta-gonal-bipyramidal and slightly disorted bicapped trigonal-prismatic environments. The LaIII ions are bridged by μ4-isophthalate ligands, forming two-dimensional layers. In the crystal structure, these layers are connected by inter-molecular O - H⋯O hydrogen bonds into a three-dimensional network.
