The reaction of the organometallic diarsene complex [Cp2Mo2(CO)4(μ,η2‐As2)] (B) (Cp = C5H5) with Ag[FAl{OC6F10(C6F5)}3] (Ag[FAl]) and Ag[Al{OC(CF3)3}4] (Ag[TEF]), respectively, yields three unprecedented supramolecular assemblies [(η2B)4Ag2][FAl]2 (4), [(μ,η12B)32B)2Ag3][TEF]3 (5) and [(μ,η12B)4Ag3][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.

作为银离子之间连接基的二叠氮化物络合物[(C5H5)2Mo2(CO)4(µ,ƞ2-As2)]的电势。

有机金属配合物diarsene [Cp的反应2的Mo 2(CO)4(μ,η 2 -As 2)]()(CP = C 5 H ^ 5)有Ag [FAL {OC 6 ˚F 10(C 6 ˚F 5)} 3 ](AG [FAL])和Ag [铝{OC(CF 33 } 4 ](AG [TEF]),分别产生三种前所未有超分子组装[(η 2 -4的Ag 2 ] [FAL] 24),[(μ,η 1:η 2 -3(η 2 -2的Ag 3 ] [TEF] 35)和[(μ,η 1:η 2 -4的Ag 3 ] [TEF] 36)。这些产物仅由配合物 B和Ag I组成。此外,化合物 56是唯一以B为连接单元的超分子组装体,也是[Ag I ] 3的首个实例通过有机金属螯合配体稳定的单元。根据DFT计算,复合物 B通过As孤对和As-Asσ-键配位到金属中心,因此显示出该二砷配体的独特特征。
