Crystal engineering, the ability to design and prepare molecular crystal structures by using the self-assembling properties of the molecules, is emerging as a powerful strategy for the construction of novel functional, nanoscale materials. In this sense, we have recently related the field of molecular crystal engineering with that of icosahedral heteroborane clusters. The purpose of the present study is to design and synthesize a series of related o-carboranyl alcohol molecules, whose chemical structure could be modified systematically to utilize the strength and directionality of the hydroxyl group of these alcohols to generate interesting supramolecular structures and study their properties. We have found a whole palette of moderate hydrogen bonding giving dimers, tetramers or infinite one-dimensional chains (some examples shown in the Figure).  G. R. Desiraju, Crystal Engineering.
