Direct Structure Determination of a Multicomponent

A threecomponent molecular cocrystal material has been prepared by a solventfree route involving mechanical grinding of the pure phases of the individual components. This material is not accessible from conventional solutionstate crystallization procedures. Due to the fact that the grinding procedure intrinsically leads to a microcrystalline powder sample, the use of powder Xray
