Abstract
New monoorgano-oxotin cages which possess bridging arsinate ligands have been prepared and characterized by X-ray and 119Sn NMR spectroscopy. The tetrameric, trimeric, and dimeric tin compounds containing arsinate ligands and six and four-membered stannoxane rings exhibit characteristics which parallel the phosphinate-bridged cages previously reported.1,2 Conversion of the tetrameric cube structure, [n-BuSn0(O2AsMe2)]4, to a mixed butterfly composition is easily accomplished by addition of arsinic, phosphinic, or carboxylic acid. For example, two butterfly compounds that we formed are: [n-BuSn(OH)(O2AsMe2)(OP(O)Me2)]2 and [n-BuSn(OH)(O2AsMe2)(OAs(O)Me2)]2. © 1989, Taylor & Francis Group, LLC. All rights reserved.
