The syntheses of rhodium(III) and iridium(III) half-sandwich complexes containing tertiary arsine and stibine ligands of the form [Cp*M(L)Cl2] (M = Rh, Ir; L = AsEt3, AsPh3, SbPh3) are reported. These compounds represent infrequent examples of rhodium and iridium metal complexes bearing arsenic or antimony ligands. All new compounds were fully characterised using 1H and 13C NMR spectroscopy, mass spectrometry
含有[Cp * M(L)Cl 2 ]形式的叔a和锑代配体的铑(III)和铱(III)半三明治复合物(M = Rh,Ir; L = AsEt 3,AsPh 3,报告了SbPh 3)。这些化合物代表了带有砷或锑配体的铑和铱金属配合物的罕见例子。使用1 H和13 C NMR光谱,质谱和单晶X射线衍射对所有新化合物进行了全面表征。DFT计算表明由(Cp * MCl 2)2和EPh 3形成配合物 (E = P,As,Sb)会放热,尽管焓驱动力按预期顺序P> As> Sb减小。
