It represents a new structure type in which distorted BiO6 octahedra are connected to each other in corner- and edge-sharing manner to form two-dimensional ~2)∞BiO_4~(5-) layers that are bridged by B atoms of BO 3 triangles giving rise to a three-dimensional ~3_∞BiBO_4~(2-) framework, with channels parallel to the 010 direction accommodating the pyramidally coordinated Pb2+ cations.
这是一种新的结构类型,在晶体结构中畸变的BiO6八面体以共边共角的方式相互连接形成二维的~2_∞BiO_4~(5-)层,层与层间通过BO3三角形中的B原子连接起来形成~3_∞BiBO_4~(2-)三维构架,存在010方向的孔道,在孔道当中填充着Pb~(2+)离子。
