Abstract

Structurally authenticated N-functionalized amides [ML2], L = N(8-quinolyl)(SiMe3), derived from the reaction of 8-(trimethylsilylamino)quinoline with MgBunBus or ZnEt2 in hexane are sublimable in vacuo at 175°C; the corresponding cadmium analogue, derived from CdCl2 and LiL, decomposes at ca. 240°C in vacuo yielding CdMe2 and a novel dimeric five coordinate silicon species [Me2Si(μ-N-C 9H6N)(μ-N-C9H6N)SiMe 2] possessing an Si2N2 ring system, Si-N bridging (mean) 1.77 Å, Si-Nneutral 2.33(1) Å.
