The selenite/hydroselenite compounds Ce(SeO{sub 3})(HSeO{sub 3}), Tb(SeO{sub 3})(HSeO{sub 3}).2H{sub 2}O, and Cs[U(SeO{sub 3})(HSeO{sub 3})].3H{sub 2}O were synthesized by hydrothermal means at 453 K from the reaction of CeO{sub 2} or Tb{sub 4}O{sub 7} or UO{sub 2} with SeO{sub 2} and CsCl (as a mineralizer). Ce(SeO{sub 3})(HSeO{sub 3}) crystallizes in the non-centrosymmetric orthorhombic space group Pca2{sub 1}. The structure comprises a two-dimensional network of interconnected CeO{sub 10} bicapped distorted square antiprisms and SeO{sub 3} trigonal pyramids. Tb(SeO{sub 3})(HSeO{sub 3}).2H{sub 2}O crystallizes in the non-centrosymmetric orthorhombic space group P2{sub 1}2{sub 1}2{sub 1}. The structure features a two-dimensional layer of interconnected TbO{sub 8} distorted square antiprisms and SeO{sub 3} trigonal pyramids. Cs[U(SeO{sub 3})(HSeO{sub 3})].3H{sub 2}O crystallizes in the centrosymmetric monoclinic space group P2{sub 1}/n. The structure consists of two-dimensional layers of interconnected UO{sub 7} pentagonal bipyramids and SeO{sub 3} trigonal pyramids. The layers in all three structures are held together by hydrogen-bonding networks. - Graphical abstract: Structure of Ce[U(SeO{sub 3})(HSeO{sub 3})].3H{sub 2}O (Cs, purple; U, black; Se, blue; O, red; O{sub w}, green; H, gray).
