Abstract:

Single-electron lithium bond complexes CH3…Li—CH3(I), H3CH2C…Li—CH3(II), (H3C)2HC…Li—CH3 (III), and (H3C)3C…Li—CH3(IV) were investigated at the B3LYP/6-311++G(d,p) and MP2/6-311++G(d,p) levels of density functional theory. Results showed that the single-electron lithium bond strength of the complexes H3CH2C…Li—CH3(II), (H3C)2HC…Li—CH3(III), and (H3C)3C…Li—CH3(IV) increased in the following order: II (-26.7 kJ·mol-1)

Key words: Single-electron lithiumbond, Single-electron hydrogen bond, Single-electron halogen bond, NBO, AIM
