Abstract

The single-crystal X-ray diffraction method was employed to characterize a rigid hydrated metal-organic framework (MOF), [Co(MA)(INA)·2HO], that displays an affinity toward water molecules under ambient conditions after dehydration. The fully dehydrated form was obtained using an environmental gas cell technique in a stepwise manner followed by its CO-pressurized structure at 298 K using in situ crystallography.

摘要

采用单晶X射线衍射方法对一种刚性水合金属有机框架（MOF）[Co(MA)(INA)·2H₂O]进行表征，该框架在脱水后于环境条件下对水分子表现出亲和力。通过环境气室技术逐步获得完全脱水形式，随后利用原位晶体学在298 K下获得其CO加压结构。
