title: Terbium(III) hydrogendiphosphate(V) tetra-hydrate.
abstract: The Tb atom of the title compound, TbHP(2)O(7)·4H(2)O, is coordinated by the O atoms of three symmetrically independent water mol-ecules and by five O atoms belonging to HP(2)O(7) (-) groups. The TbO(8) polyhedra are inter-connected by the diphospate anions, forming a three-dimensional network which is additionally stabilized by O-H⋯O hydrogen bonding between water mol-ecules and O atoms of the HP(2)O(7) (-) anions. Uncoordinated water mol-ecules are situated in channels and are connected via hydrogen bonds with the framework.
