The reaction of [H(OEt2)2][B(C6F5)4] with Zn[N(SiMe3)2]2, MgBu2, and Mg[N(SiMe3)2]2}2 in diethyl ether proceeds in very high yields to give the salts [(Et2O)3ZnN(SiMe3)2][B(C6F5)4] (2), [(Et2O)3MgnBu][B(C6F5)4] (3), and [(Et2O)3MgN(SiMe3)2][B(C6F5)4] (4), respectively. The structures of 2 and 4 were determined by X-ray crystallography; the compounds contain distorted-tetrahedral metal centers and
