In the title binuclear complex, [Li2(C27H36N2)2I2], the unique LiI cation is coordinated by two iodide anions and one ylidene C atom from a 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene ligand in a distorted trigonal–planar geometry. The two symmetry-related iodide anions bridge two LiI cations, forming an inversion dimer in which the Li2I2 plane is nearly perpendicular to the imidazol-2-ylidene ring, with a dihedral angle of 85.5 (3)°. No hydrogen bonding is observed in the crystal.
