Crystal structure and Hirshfeld surface analysis of 2-picolyllithium·3thf

In the title compound, (2-methylidene-1,2-dihydropyridinium-κ N )tris(tetrahydrofuran-κ O )lithium, [Li(C 6 H 6 N)(C 4 H 8 O) 3 ], the lithium ion adopts a distorted LiNO 3 tetrahedral 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 methylene group of one of the thf ligands is disordered over two orientations. In the crystal, a weak C—H...O interaction 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.
