C - H⋯X (X = O, N or π) interactions in benzyl carbamate

Abstract

The crystal packing and inter-action energy of benzyl car-bam-ate, C 8H 9NO 2, have been analysed in detail by the PIXEL method. Benzyl carbamate forms layers of hydrogen-bonded mol-ecules, with the layers connected by weaker C - H⋯π inter-actions. According to the PIXEL analysis, combinations of C - H⋯X (X = O, N or π) inter-actions are comparable in energy with hydrogen bonding. These inter-actions are necessary for explaining the geometry and the assembly of the layers.© 2012 International Union of Crystallography.
