Abstract
Slow evaporation of a 1: 1 or 1: 2 molar solution of p-nit roaniline and p-nitrophenol in a mixture of dichloromethane and n-hexane deposited two kinds of single crystals which were mechanically separated: 2: 1 molecular crystal A and 1: 3 molecular crystal B. In a similar manner a 1: 1 or 2: 1 molar solution of m-nitroaniline and m-nitrophenol in a mixture of chloroform and petroleum ether deposited the single crystals of 2 : 1 molecular crystal C. The crystal structures of A, B and C were found to be isomorphic to those of p-nitroaniline, p-nitrophenol (b form) and m-nitroaniline, respectively. The characteristics of the crystal structures of A, B and C are discussed.Keywords
