The reactions of the heteroleptic lithium amide [Li-3(mu-hmds)(2)(mu,mu-hpp)] (1), where [hmds](-) = hexamethyldisilazide and [hpp](-) = hexahydropyrimidopyrimidide, with MnCl2, CoCl2 or ZnBr2 result in the formation of the separated ion-pairs [MLi7(mu(8)-O)(mu,mu-hpp)(6)](+)[A](-), which each consist of a {MLi7} oxo-centred cube structural motif (M = Mn 2, Co 4, Zn 5), with each face of the cube being bridged by an [hpp](-) ligand. In the case of M = Mn and Co, the counter ion, [A](-), is the pentagonal anionic inverse crown [{Li(mu-hmds)}(5)(mu(5)-Cl)](-) (3), whereas the reaction with M = Zn produces the known tris-amido zincate [Zn(hmds)(3)](-) counter anion.
