ResumoESR spectra are reported for the previously unobserved Na+HCl− complex. In an argon matrix at ≈ 30 K, the ESR spectra are isotropic and characteristic of a motionally averaged radical. The experimental parameters are g0 = 2.0008(3) with hf splitting constants aH = 417.01(8) G and aCl = 40.18(3) G for hydrogen and 35Cl, respectively. As with the isovalent K+HCl− complex, the unpaired electron is entirely delocalized in a σ∗ orbital on HCl−. The influence of the cation is indicated by a substantial increase in spin population on hydrogen as Na+ → K+.
