To reveal the structural conditionality for anomalies in physical properties, including dielectric and optical properties, diffraction studies of K9H7(SO4)8·H2O crystals were performed using synchrotron radiation in the temperature range 293–450 K and determined at 405 K, taking H atoms into account. The results indicate that the occurrence of high conductivity in K9H7(SO4)8·H2O crystals with a temperature increase is associated with the outward diffusion of water molecules, hydrogen-bond network rearrangement and the formation of channels for the possible motion of K+ions. A rearranged system of hydrogen bonds consists of permanent bonds and partly of dynamically disordered bonds. Hydrogen-bond rearrangement and the hindered back diffusion of water to the crystal bulk stabilize the high-temperature crystal structure right down to room temperature.

An unpredicted fourfold screw N—H...O hydrogen bond C(4) motif in a primary dicarboxamide (trans-cyclohexane-1,4-dicarboxamide, C8H14N2O2) was investigated by single-crystal X-ray diffraction and IR and Raman spectroscopies. Electron-density topology and intermolecular energy analyses determined from ab initio calculations were employed to examine the influence of weak C—H...O hydrogen-bond interactions on the peculiar arrangement of molecules in the tetragonal P43212 space group. In addition, the way in which the co-operative effects of those weak bonds might modify their relative influence on molecular packing was estimated from cluster calculations. Based on the results, a structural model is proposed which helps to rationalize the unusual fourfold screw molecular arrangement.
