Synthesis and structures of some bimetallic (Li/Ca, Li/Zn, Li/Li) diamides derived from 1,2-bis(neopentylamino)benzene and of Li2[{N(SiMe2NPri2)}2C6H4-1,2](thf)3
Abstract
The following crystalline, or microcrystalline (4), metal diamides have been prepared under mild conditions from the N,N′-disubstituted 1,2-diaminobenzene [{N(R)H}2C6H4-1,2] (H2L: R = CH2But; H2L′: R = SiMe2NPri2): [Li(thf)(µ-L)(µ-I)Ca(thf)] (1), [Li(thf)4][{Zn(µ-L)}3(µ3-Cl)] (2), [Li(thf)4][Zn(L)2] (3), [{Li(OEt2)(µ-L)Zn}2(µ-L)] (4), [Li(OEt2)(µ-L)Zn(µ-L)Zn(LH)] (5) and [Li(thf)(µ-L′)Li(thf)2] (6). Compounds 1–5 were obtained from [Li2(L)] and
