The crystal structure of the title compound, {[Er₂(C₂H₄O₆PS)(OH)₃(H₂O)]·H₂O}_n, consists of two Er³⁺ ions, one (C₂H₄O₆PS)³⁻ ion, three OH⁻ ions, and two water mol­ecule. The Er³⁺ ions form ErO₈ polyhedra., which are connected by μ- and μ₃-O atoms. Thus, inorganic Er–O–Er layers of edge- and face-sharing polyhedra are observed. Whereas most often in metal phosphono­sulfonates the organic linker bridges adjacent layers, in the title compound, the (O₃PC₂H₄SO₃)³⁻ anion is only connected to one Er–O–Er layer. Short interatomic O⋯O distances [2.898 (8), 2.997 (14) and 2.768 (10) Å] indicate hydrogen bonding between the layers. The noncoordinated water mol­ecules are located between the layers.

Poly[[diaqua-μ(2)-hydroxido-(μ(7)-2-phos-pho-nato-ethane-sulfonato)-dicopper(II)] trihydrate]

The crystal structure of the title compound, [Cu₂(C₂H₄O₆PS)(OH)(H₂O)₂]·3H₂O, consists of two Cu²⁺ ions, one (O₃PC₂H₄SO₃)³⁻ ion and one OH⁻ ion, as well as five water mol­ecules, two of which are coordinated to Cu²⁺. The Cu²⁺ ions are coordinated by six O atoms. The CuO₆ polyhedra are connected by μ- and μ₃-O atoms into zigzag chains along the b axis. These chains are further connected by –CH₂CH₂– groups to form layers, in turn building a three-dimensional framework via hydrogen bonding.
