the crystal structures of Ca3(SeO4)(TeO3)2, Ca3(SeO4)(Te3O8), Cd3(SeO4)(Te3O8), Cd3(H2O)(SO4)(Te3O8), and Sr3(H2O)2(SeO4)(TeO3)2 are metal-oxotellurate(IV) layers connected by bridging XO4 tetrahedra and/or by hydrogen-bonding interactions involving hydroxyl or water groups, whereas Cd4(SO4)(TeO3)3 and Cd5(SO4)2(TeO3)2(OH)2 crystallize as framework structures. Common to all crystal structures is the
