33. 2O are extremely weakly diffracting. The crystals in addition are exceptionally fragile and require very careful handling. Upon exposure to air, the crystals begin to lose crystallinity almost immediately and degrade even when coated in protective oil. This fragility along with the weakly diffracting nature of the crystals made the data collection, refinement of the structure, and the modeling of solvent molecules particularly challenging. Repeated attempts were made to obtain high quality crystallographic data including the use of synchrotron radiation. However, in each case, the weakly diffracting nature of the crystals did not allow for the unambiguous assignment of water molecules.
