NO3–⋯NO3– and NO3–⋯π interactions in the crystal of urea nitrate

Abstract

The geometrical and energy aspects of the NO3−⋯NO3− and NO3−⋯π-system interactions were analyzed in the framework of the charge density investigation in crystalline urea nitrate. The results obtained have revealed that relatively weak anion–anion and anion–π (cation) contacts contribute greatly to the stabilization of the layered structure for this particular ionic material.
