Fig. 6: The weak interactions in HOF-NF.
From: Taming nitroformate through encapsulation with nitrogen-rich hydrogen-bonded organic frameworks

a Noncovalent interaction (NCI) plots of NF1 (left) and NF2 (right) in HOF-NF, the surfaces are colored on a blue-green-red scale indicating strong attractive interactions, weak attractive, and strong nonbonded overlap, respectively; b Simulation of a Hirshfeld surface in a single ring; c 2D fingerprint plot generated by Hirshfeld surface.
