Abstract

Structurally authenticated N-functionalized amides [ML₂], L = N(8-quinolyl)(SiMe₃), derived from the reaction of 8-(trimethylsilylamino)quinoline with MgBuⁿBu^s 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-N_neutral 2.33(1) Å.
