摘要：
High-pressure/high-temperature conditions were used to synthesize the new rare earth oxoborates Ln(4)B(6)O(15) (Ln = Dy, Ho; 8.0 GPa, 1000degreesC) and alpha-Ln(2)B(4)O(9) (Ln = Eu, Gd, Tb, Dy; 10.0 GPa, 1150degreesC) in a Walker-type multianvil apparatus. In addition to their new compositions, which were unattainable under normal pressure conditions, the structures exhibit the new structural motif of edge sharing BO4 tetrahedra leading to a structural extension of oxoborate chemistry.
