complexes [(η6-arene)Ru(μ-Cl)Cl]2 and [Cp*M(μ-Cl)Cl]2 (M = Rh, Ir). The cationic complexes were characterized by FT-IR, UV/Vis, and 1H-NMR spectroscopy as well as mass spectrometry. X-ray crystallographic studies of these complexes reveal piano-stool-like arrangements around the metal atoms with six-membered metallacycles in which L1 and L2 act as a N, S- and N, N' chelating ligands, respectively.
双齿配体苯甲酰(2-吡啶基)硫脲(L1)是通过苯甲酰异硫氰酸酯与伯胺(2-氨基吡啶)反应制备的,但与仲胺双(2-吡啶基)胺反应得到了意想不到的产物双(2-氨基吡啶)吡啶基)苯甲酰胺(L2)。通式[(η6-芳烃)Ru(L)Cl]+其中,L=L1,芳烃=苯(1);对伞花烃 (2); L=L2,芳烃=苯(5);对伞花烃 (6)} 和 [Cp*M(L)Cl]+ 其中,L = L1,M = Rh (3),Ir (4);L = L2, M = Rh (7), Ir (8)},分别由配体 L1 和 L2 与前体配合物 [(η6-芳烃)Ru(μ-Cl)Cl]2 和 [Cp] 反应形成*M(μ-Cl)Cl]2 (M = Rh, Ir)。阳离子配合物通过 FT-IR、UV/Vis 和 1H-NMR 光谱以及质谱进行表征。
