Poly[hexa-aquabis(μ3-terephthalato)(μ2- terephthalato)diytterbium(III)]

Abstract

In the title two-dimensional coordination polymer, [Yb2(C 8H4O4)3(H2O) 6]n , the unique YbIII ion is eight-coordinated in a distorted dodeca-hedral coordination geometry by three water O atoms and five O atoms from carboxyl-ate groups belonging to four different terephthalate ligands. One of the terephthalate ligands is located around an inversion center. The coordination polymers are parallel to (121) and are connected by O-H⋯O hydrogen bonds into a three-dimensional framework.
