Anion photoelectron spectroscopy and CCSD(T) calculations of the Cl−⋯N2 complex

• Gas phase anion photoelectron spectrum of the chloride–nitrogen complex is presented.
• CCSD(T) calculations determine geometries of both the anion and neutral complexes.
• Electron detachment energies agree well between experiment and calculations.
• Stability of halide–nitrogen complexes are shown to follow periodic trends.
