A Mn²⁺-based metal–organic framework (coordination porous framework-5, CPF-5) can serve as a crystalline sponge for single crystal X-ray structural characterization of a variety of compounds using a combination of coordinative alignment and second coordination sphere interactions (e.g., hydrogen bonding). This technique requires only a conventional X-ray source to obtain high quality crystallographic data.

协调排列，以实现多功能分子结晶海绵中的有序客体分子

基于Mn ²⁺的金属有机骨架（配位多孔骨架5，CPF-5）可以用作结晶海绵，用于结合协调配位和第二配位球对多种化合物进行单晶X射线结构表征相互作用（例如氢键）。该技术仅需要常规的X射线源即可获得高质量的晶体学数据。
