Potassium rubidium cobalt(II)/titanium(IV) tris-(orthophosphate), Rb0.743K0.845Co0.293Ti1.707(PO4)3, has been obtained using a high-temperature crystallization method. The obtained compound has a langbeinite-type structure. The three-dimensional framework is built up from mixed-occupied (Co/Ti(IV))O6 octa-hedra (point group symmetry .3.) and PO4 tetra-hedra. The K(+) and Rb(+) cations are statistically distributed over two distinct sites (both with site symmetry .3.) in the large cavities of the framework. They are surrounded by 12 O atoms.
通过高温结晶法制备了铷钾钴（II）/钛（IV）三（正磷酸盐），即Rb0.743K0.845Co0.293Ti1.707(PO4)3。所得到的化合物具有白钾镁矾型结构。三维骨架由混合占据的（Co/Ti（IV））O6八面体（点群对称性.3.）和PO4四面体构成。K(+)和Rb(+)阳离子统计分布在骨架大空洞中的两个不同位置（两者的位置对称性均为.3.）。它们被12个O原子包围。
