Crystal structure of bis[3-amino-4-(4-aminophenoxy)] diphenylsulfone

Abstract

1. X-ray structural analysis has established that the molecular structure of bis[3-amino-4-(4-aminophenoxy)]diphenylsulfone exhibits a nonplanar twisted structure, in which the four cyclic fragments are nearly perpendicular to one another. 2. The crystal structure features an extended system of intermolecular hydrogen bonds of the type N-H...O, which unite the molecules in an infinite three-dimensional framework.
