title: Crystal structure of bis-{N-[(di-ethyl-amino)-dimethyl-sil-yl]anilido-κ(2) N,N'}zinc.
abstract: 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 mol-ecule is generated by twofold rotation symmetry. The central Zn(II) atom is N,N'-chelated by each of the two N-silylated anilide ligands in a highly distorted tetra-hedral environment. Two N-Si-N ligands are arranged in a cis fashion around the Zn(II) atom. The Zn-Namine bonds [2.2315 (12) Å] are much longer than the Zn-Nanilide bonds [1.9367 (11) Å].
