The influence of number of nitrogen atoms on the NMR data in aromatic azine⋯HF complexes

- |ΔE|, ρBCP, E2 and the basicity of ring decrease with increasing the number of nitrogen atoms in the ring.
- The continuum of N⋯H interactions ranging from weak to medium hydrogen bonds has been observed.
- Unlike 1JH-F and 1hJN⋯H, |2hJN⋯F| and δH decrease with increasing the number of nitrogen atoms in the ring.
