摘要
The crystal structure of a new ternary borate, lead gallium boron tetraoxide, PbGaBO4, has been determined by X-ray diffraction using a single-crystal grown from a PbO flux. The structure consists of infinite [010] chains of edge-sharing GaO6 octahedra bridged by BO3 triangles. The Pb2+ cations and their stereoactive lone pair occupy the apex of PbO4 square pyramids. The structure represents a new structure-type for anhydrous orthoborates. Bond-valence analysis reveals the presence of strain within the octahedral chains.
