Considering properties of water and benzene molecules, one can expect very different benzene/benzene and water/water interactions. Benzene does not have a dipole moment, while water has. Quantum chemical calculations showed that minima on potential surface of water/water interactions is hydrogen bond, where dipole moment of water plays important role. The calculations show that the minima on potential surface for benzene/benzene interactions are stacking (parallel displaced) geometry and T-shaped geometry. Analysis of the data in the crystal structures in the Cambridge Structural Database (CSD) revealed the most frequent benzene/benzene and water/water geometries. Majority of the benzene/benzene interactions in the crystal structures in the CSD are tacking interactions with large horizontal displacements, and not geometries that are minima on benzene/benzene potential surface. Large number of the water/water contacts in the CSD are hydrogen bonds, 70% of all attractive water/water inte...ractions. In addition water/water contacts with two water forming antiparallel interactions are 20% of all attractive water/water contacts. In these contacts O-H bonds of water molecules are in antiparallel orientation (Fig. 1). In benzene/benzene interactions at large horizontal displacements two C-H bonds also are in the antiparallel orientation (Fig. 1).
