We present an approach to understanding crystal packing via 'energy frameworks', that combines efficient calculation of accurate intermolecular interaction energies with a novel graphical representation of their magnitude. In this manner intriguing questions, such as why some crystals bend with an applied force while others break, and why one polymorph of a(More)
A charge-assisted hydrogen-bonding network involving N-H⋯O and O-H⋯O hydrogen bonds stabilizes the crystal of the title salt, C5H8N3 (+)·H2PO4 (-). The dihydrogen phosphate anions form one-dimensional chains along [100], via O-H⋯O hydrogen bonds. The 2-amino-4-methyl-pyrimidinium cations are linked to these chains by means of two different kinds of N-H⋯O(More)
