Crystals of a new, noncentrosymmetric oxide, orthoborate have been grown, and the structure of the material has been determined by X-ray diffraction techniques. The material crystallizes in the space group P321. The structure consists of a continuous, three-dimensional gallium borate framework with channels that run parallel to the [001] direction wherein the potassium atoms are located. The triangular orthoborate groups and the trigonal bases of the gallium-centered tetrahedra form two-dimensional layers through Ga-O-B linkages; these layers are parallel to (001) planes. Ga-O-Ga linkages interconnect adjacent layers to complete the three-dimensional framework. Use as a nonlinear optical material is unlikely because of nonoptimal alignment of the triangular orthoborate groups. In this paper, the authors report the synthesis, thermal properties, and crystal structure of K{sub 2}Ga{sub 2}(BO{sub 3}){sub 2} and describe its potential as a nonlinear optical material.
