Popis: It is shown that enthalpies of nitrogen fluorides and oxo fluorides deviate markedly from enthalpies of corresponding hydroxo compounds, whereas there is good agreement (circa 2%) between carbon mono, di and trifluoro compounds and their hydroxo analogues. The extent of deviation correlates with the extra number of lone pair repulsions of fluoro over oxo compounds. The enthalpy of NF 4 + (g) can be extrapolated from the other (N,F) and (N,O,F) compounds. The enthalpies of solid NF 4 + salts are close to those of corresponding NO 2 + salts and from this an exothermic heat of formation for NF 4 + F − is predicted.
