Coordinative Alignment To Achieve Ordered Guest Molecules in a Versatile Molecular Crystalline Sponge

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.
