Abstract
In the title two-dimensional coordination polymer, [Yb2(C8H4O4)3(H2O)6]n, the unique YbIII ion is eight-coordinated in a distorted dodecahedral coordination geometry by three water O atoms and five O atoms from carboxylate 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.
