许多分子材料不能通过常规的晶体生长从溶液中制备为“纯”（非溶剂合物）晶相，这是由于溶剂合物结构的容易形成。在这种情况下，可以通过固态去溶剂化方法获得纯相，尽管这种方法通常与晶体完整性的损失相关，产生纯相的微晶粉末。本文展示了现代粉末X射线衍射技术的效用，在这种情况下，获得结构的理解，专注于一个特定的成员的结构家族，是更广泛的相关范围内的晶体工程和设计。
Many molecular materials cannot be prepared as a “pure” (nonsolvate) crystalline phase by conventional crystal growth from solution due to the facile formation of solvate structures. In such cases, it may be possible to obtain the pure phase by a solid-state desolvation process, although such processes are generally associated with loss of crystal integrity, yielding a microcrystalline powder of the pure phase. This paper demonstrates the utility of modern powder X-ray diffraction techniques for obtaining structural understanding in such cases, focusing on a particular member of a structural family that is of wider relevance within the context of crystal engineering and design.
