Single crystals of strontium tetra-cobalt tris-(orthophosphate) hydroxide, SrCo(OH)(PO), were grown serendipitously under hydro-thermal conditions at 473 K. The crystal structure consists of undulating chains of edge-sharing [CoO] octa-hedra that are linked into (010) layers by common vertices between chains. Adjacent layers are linked along [010] into a framework structure by tetra-hedral [CoO] units and by PO tetra-hedra. The framework delimits channels extending along [100] in which the eleven-coordinate strontium cations are situated. Bifurcated O-H⋯O hydrogen bonds of weak strengths consolidate the crystal packing. The title compound was also characterized by infrared spectroscopy.
四钴三（正磷酸）氢氧化锶单晶，即SrCo(OH)(PO)，在473 K的水热条件下意外生长而成。晶体结构由共享边的[CoO]八面体的起伏链组成，这些链通过链间的公共顶点连接成(010)层。相邻层通过四面体[CoO]单元和PO四面体沿[010]连接成框架结构。该框架界定了沿[100]延伸的通道，十一配位的锶阳离子位于其中。强度较弱的分叉O-H⋯O氢键巩固了晶体堆积。该标题化合物还通过红外光谱进行了表征。
