Bis-amido- complexes of heavier Group 15 metal chlorides with the sterically hindered, N-functionalised amido ligand, [{2-(6-Me)C5H3N}NSiMe3]−
摘要:
The reaction of the lithium amide, [2-(6-methyl)pyridyl] trimethylsilylamido-lithium, with antimony(III) or bismuth(III) trichloride in diethyl ether gives the bis-amido antimony(III) or bismuth(III) chloride [{2-(6-Me)C5H3N}NSiMe3]MCl, [M = Sb (1) or Bi (2)] as colourless or yellow prisms respectively. The antimony complex is monomeric in the solid state whereas the bismuth complex is dimeric with bridging chlorides. (C) 1998 Elsevier Science Ltd. All rights reserved.
