AA -di(m-nitrophenyl)urea or DNPU (dinitrophenyl urea) exists in three concomitant polymorphic forms (a, and S) of different colours [25], It readily forms solvates and cocrystals with compounds having strong to moderate hydrogen bond acceptors [26], The characteristic urea network is absent except in the noncentrosymmetric /3-polymorph of DNPU whereas a and y polymorphs are sustained by N-H- -Onitro H bonds. We examined hydrogen bond competition in crystal structures of N-X-phenyl-A -p-nitrophenyl urea, abbreviated as PNPU-X [27] (Figure 5.15). A variety of X groups were considered. [Pg.160]
