Evidence for genuine hydrogen bonding in gold(I) complexes

Solvation involves different types of intermolecular interactions: hydrogen bonding, ion–dipole interactions, and van der Waals forces (which consist of dipole–dipole, dipole–induced dipole, and induced dipole–induced dipole interactions). Which of these forces are at play depends on the molecular structure and properties of the solvent and solute.
