[Li(Et2O)2]2H2)21, [Li2(Et2O)3] H2)27, [Li(Et2O)2]2H(CH3))210, [Li(TMEDA)]2H2)213 and [Li2(Et2O)2.3] H2)214 were synthesized by treatment of ZnCl2 with the dilithium compounds LiCH2CH2CH2CH2Li, LiCH(CH3)-CH2CH2CH 2Li, LiCH(CH3)CH2CH2CH(CH3)Li, LiCH2CH(CH3)CH2CH2Li or LiCH2CH(CH3)CH(CH3)CH2Li in diethyl ether. Some of these complexes (7, 10) were also readily obtained by a one-pot reaction of the corresponding
