Two new structural types of BaREGeO4(OH) and BaRE10(GeO4)4O8 (RE=Ho3+-Er3+) single crystals were synthesized via high temperature and high pressure hydrothermal synthesis. The crystal structure of BaREGeO4(OH) was found to crystallize in the orthorhombic space group Pbca and contain a one-dimensional chain (1-D) of rare-earth polyhedra linked through edge sharing of oxygen atoms. High density BaRE10(GeO4)4O8 crystals crystallize in monoclinic space group C2/m and feature a sheet like arrangement of rare-earth oxide polyhedra with a Keggin-like arrangement. Barium polyhedra and isolated GeO4 units aid in connecting the metal oxide framework to extend it in three-dimensional (3-D) space.
