In solvents with a low D that also lack the ability to solvate ions (hydrocarbons, halohydrocarbons) the interaction does not go beyond the initial hydrogen bond or contact ion pair formation.
Experimentally determined structures of small contact ion pairs in solution are very rare and sometimes lacking in complete research fields.
