Li-pyridazine (1,2-C4H4N2) is produced in laser-vaporization supersonic molecular beams and studied with pulsed field ionization-zero electron kinetic energy (PFI-ZEKE) spectroscopy and density functional theory. From the PFI-ZEKE spectrum, adiabatic ionization energy of the neutral complex is measured to be 4.6953 ± 0.0006 eV; metal-ligand and ligand-based vibrations in a frequency range of 200-1600 cm-1 are determined for the ionized species. By comparing the spectroscopic measurements with the density functional theory calculations, the structure of the Li complex is determined to be planar, with metal binding to both nitrogen atoms of pyridazine in σ fashion.
