Solid-State Complexation Reaction between p-Benzoquinone and p-Nitroaniline

Abstract

Reaction between p-benzoquinone (p-BQ) and p-nitroaniline (p-NA) occurs both in the solid state and solution, forming a weak molecular addition compound (p-BQ)₁ · (p-NA)₁ in which the two components are associated by hydrogen bonding between one O atom of p-BQ and one H atom of the NH₂ group of p-NA. Single crystals of the reaction product grown from solution belong to a monoclinic system.
