Abstract The crystal structures of the title compounds are reported. Me2Si[N(SiMe3)2]2: Space group Pbcn, Z = 4, lattice dimensions at 213 K: a = 1487.8(1), b = 1299.4(1), c = 1259.7(1) pm. The compound forms monomeric molecules with crystallographic C2 symmetry and Si-N bond lengths of 177.9(3), 171.6(3) and 175,2(3) pm. [Me2Si(NPh)(NHPh)Li·OEt2]2: Space group P21/n, Z = 2, lattice dimensions at 190 K: a = 1082.7(3), b = 1038.8(2), c = 1641.3(4) pm, β = 91.350(3)°. The compound forms centrosymmetric dimeric molecules in which the lithium atoms are members of a Li2N2 ring with Li-N bond lengths of 206.6(2) and 213.5(2) pm. The hydrogen atom at the nitrogen atom of the HNPh- group is not involved in hydrogen bridging bonds.
