The crystal is monoclinic, space group P2 1/n with a =1 1243(3) nm, b =2 4853(2) nm, c =1 2962(1) nm, β =95 08(1)°, V =3 608(1) nm 3, Z =4, D c=1 757 g/cm 3. Each of the erbium ion is coordinated by eight water molecules. The complex is of polymeric structure with the octaaqua erbium complex species connected by 1,4 dioxane moieties through hydrogen bonds.展开更多
