Abstract: During our research into novel nonlinear optical materials using 1,10-phenanthroline as an appending ligand on lanthanide iodates, crystals of an infinite layered Dy^III iodate compound, Dy(IO₃)₃(H₂O)·H₂O, were obtained under hydrothermal conditions. The Dy^III cation has a dicapped trigonal prismatic coordination environment consisting of one water O atom and seven other O atoms from seven iodate anions. These iodate anions bridge the Dy^III cations into a two-dimensional structure. Through O-HO hydrogen bonds, all of these layers stack along [111], giving a supramolecular channel, with the solvent water molecules filling the voids.
