The Potential of the Diarsene Complex [(C5 H5 )2 Mo2 (CO)4 (μ,η2 -As2 )] as a Connector Between Silver Ions.

ABSTRACT: The reaction of the organometallic diarsene complex [Cp2 Mo2 (CO)4 (μ,η2 -As2 )] (B) (Cp = C5 H5 ) with Ag[FAl{OC6 F10 (C6 F5 )}3 ] (Ag[FAl]) and Ag[Al{OC(CF3 )3 }4 ] (Ag[TEF]), respectively, yields three unprecedented supramolecular assemblies [(η2 -B)4 Ag2 ][FAl]2 (4), [(μ,η1 :η2 -B)3 (η2 -B)2 Ag3 ][TEF]3 (5) and [(μ,η1 :η2 -B)4 Ag3 ][TEF]3 (6). These products are only composed of the complexes B and AgI . Moreover, compounds 5 and 6 are the only supramolecular assemblies featuring B as a linking unit, and the first examples of [AgI ]3 units stabilized by organometallic bichelating ligands. According to DFT calculations, complex B coordinates to metal centers through both the As lone pair and the As-As σ-bond thus showing this unique feature of this diarsene ligand.
