The Coordination Behaviour of the Nitrogen Bases R—CN (R = H, Cl, I, CH 3 ) and Pyridine towards AsF 5 in Solution The coordination behaviour of the nitriles R—CN (R = H, Cl, I, CH 3 ) and of pyridine towards the strong Lewis acid AsF 5 in solution is investigated and discussed on the basis of the hardsoft acid‐base (HSAB) principle. Solution equilibria are studied by means of 1 H‐NMR spectroscopy. For the equilibrium of HCN, ICN, and AsF 5 with the corresponding coordinated Lewis acid—Lewis base adducts the estimated value for the equilibrium constant is in good agreement with the experimental data.
