The title complex, [Li4(C17H14N 4)2(C4H8O)4], bears a novel tetradentate diamido ligand. In the tetranuclear centrosymmetric complex molecule, the metal atoms exhibit two kinds of coordination modes. The middle two Li+cations are coordinated by four N (ligand) and one O (tetrahydrofuran, THF) atoms, resulting in a distorted square-pyramidal geometry. The outer two Li+cations are in distorted tetrahedral environments consisting of three N (ligand) and one O (THF) atoms. The Li-N bond lengths vary from 2.020 (7) to 2.441 (6)Å. Source

The title compound, [Cu2(C12H21N 2Si)2], is a binuclear CuI complex. The dimeric mol-ecule has an inversion center located at the mid-point of the Cu - Cu bond [Cu - Cu = 2.7209 (7) Å]. The bidentate ligand behaves in an N:N′-bridging mode, coordinating the metal atoms. The N - Cu - N unit is close to being linear [176.60 (8)°]. The two N atoms exhibit different affinities for the metal atom. The Cu - Namino bond is longer than the Cu - Nanilido bond by 0.079 Å. The core of the mol-ecule, the [Cu - N - Si - N]2 eight-membered ring, adopts a chair configuration. Source

In the monomeric title titanium(III) compound, [Ti(C12H 21N2Si)2Cl], the metal atom is surrounded by two N-silylated anilide ligands in an N,N″-chelating mode. The two ends of the N - Si - N chelating unit exhibit different affinity to the metal center. The Ti - Namine bond is longer than the Ti - Nanilide bond by about 0.29 Å. The two ligands are arranged trans to each other and the molecule demonstrates a pseudo-twofold rotation along the axis of the Ti - Cl bond. The five-coordinate Ti atom demonstrates a highly distorted trigonal-bipyramidal geometry. Source

The title zinc amide, [Zn(C12H21N2Si)2], was prepared by the metathetical reaction of [LiN(SiMe2NEt2)(C6H5)]2 with zinc dichloride. It is mononuclear and the molecule is generated by twofold rotation symmetry. The central ZnII atom is N,N'-chelated by each of the two N-silylated anilide ligands in a highly distorted tetrahedral environment. Two N - Si - N ligands are arranged in a cis fashion around the ZnII atom. The Zn - Namine bonds [2.2315(12)Å] are much longer than the Zn - Nanilide bonds [1.9367(11)Å]. Source

The mononuclear Ni II amide, [Ni(C 12H 21N 2Si) 2], has the Ni II atom N,N′-chelated by the N-silylated anilinide ligands. The ligands are arranged cis to each other and obey the C 2-symmetry operation. The two ends of the N-Si-N chelating unit exhibit different affinities for the metal atom: the Ni-Nanilinide bond length is 1.913 (3) Å and Ni-Namine is 2.187 (3) Å. The four-coordinate Ni II ion demonstrates a distorted tetra-hedral geometry. Source
