In the title compound, (2-methyl-idene-1,2-di-hydro-pyridinium-κN)tris-(tetra-hydro-furan-κO)lithium, [Li(C6H6N)(C4H8O)3], the lithium ion adopts a distorted LiNO3 tetra-hedral coordination geometry and the 2-picolyl anion adopts its enamido form with the lithium ion lying close to the plane of the pyridine ring. A methyl-ene group of one of the thf ligands is disordered over two orientations. In the crystal, a weak C-H⋯O inter-action generates inversion dimers. A Hirshfeld surface analysis shows that H⋯H contacts dominate the packing (86%) followed by O⋯H/H⋯O and C⋯H/H⋯C contacts, which contribute 3% and 10.4%, respectively.
Keywords: 2-methylpyridyllithium; 2-picolyllithium; Hirshfeld surface analysis; crystal structure.
