Isolation and authentication of a sodium bispyrazolylaluminate
摘要:
Reaction of [Na(Me(2)pz)(thf)](4) (2) with [(Me(2)pz)AlMe2](2) in THF generates sodium bispyrazolylaluminate [Na{Al(Me(2)pz)(2)Me-2}](infinity) (1), the first example of a structurally characterized aluminum analog of a polypyrazolylborate. The X-ray structure of complex 1 shows in the solid state unusual Na-CH3-Al bridges and pyrazolyl eta(5)-coordination to sodium. (C) 2004 Elsevier B.V. All rights reserved.
