The tripodal, tetradentate tris(1-(diphenylphosphanyl)-3-methyl-1H-indol-2-yl)phosphane PP3 -ligand 1 stabilizes Ru in the RuII , RuI , and Ru0 oxidation states. The octahedral [(PP3 )RuII (Cl)2 ] (2), distorted trigonal bipyramidal [(PP3 )RuI (Cl)] (3), and trigonal bipyramidal [(PP3 )Ru0 (N2 )] (4) complexes were isolated and characterized by single-crystal X-ray diffraction, NMR, EPR, IR, and ESI-MS
三脚架四齿三(1-(二苯基膦基)-3-甲基-1H-吲哚-2-基)膦PP3-配体1使Ru稳定在RuII,RuI和Ru0氧化态中。分离出八面体[(PP3)RuII(Cl)2](2),扭曲的三角双锥体[[PP3] RuI(Cl)](3)和三角双锥体[(PP3] Ru0(N2)](4)配合物并通过单晶X射线衍射,NMR,EPR,IR和ESI-MS进行表征。开壳的金属基RuI络合物3和闭壳的RuO络合物4都经历从二氯甲烷容易地(净)提取Cl原子,导致分别形成相应的RuII和RuI络合物2和3。
