Abstract

A new method of inducing the crystallisation of metastable polymorphs by isomorphous templating has been developed and used to reproduce the crystallisation of CBZ-V on the surface of DHC-II. Studies of the growth of CBZ-V on DHC-II single crystals show crystals growing laterally and vertically on DHC-II surfaces without any significant face selectivity. The generality of this computationally inspired crystallisation approach is demonstrated by producing the first crystals of an entirely new polymorph of cyheptamide, which is isomorphous to both DHC-II and CBZ-V.
