Crystal structure of di-μ-iodido-bis­{[1,3-bis­(2,6-diiso­propyl­phen­yl)imidazol-2-yl­idene]lithium}

In the title binuclear complex, [Li(2)(C(27)H(36)N(2))(2)I(2)], the unique Li(I) 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 brid...

Sumario:In the title binuclear complex, [Li(2)(C(27)H(36)N(2))(2)I(2)], the unique Li(I) 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 Li(I) cations, forming an inversion dimer in which the Li(2)I(2) 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.
