Diethylcyanamide is added to a hexanes solution of lithium diethylamide [LiN(CH(2)CH(3))(2)] resulting in the formation of lithium 1,1,3,3-tetraethylguanidinate, [Li(mu-TEG)](6) (1). Upon successful isolation of 1, the metathesis reaction of MX(2) (MX(2) = MnBr(2), FeBr(2), CoBr(2), and ZnCl(2)) with [Li(mu-TEG)](6) and
