The dinuclear complex [(C6F5)2Pt(μ-PPh2)2Pt(NCCH3)2] (1) is described and fully characterised. Complex 1 reacts with 2,2′-bipyrimidine and cis-[M(C6F5)2(THF)2] to form the di-, tri- and tetranuclear complexes 2, 3 and 4, respectively, depending on the ratio of reagents and the type of metal (M = Pt, Pd). Complex 1 reacts with KCN to form the anionic dinuclear complex [PPh3(CH3)]2[(C6F5)2Pt(μ-PPh2)2Pt(CN)2]
双核复合物 [(C6F5)2Pt(μ-PPh2)2Pt(NCCH3)2] (1) 被描述和充分表征。配合物 1 与 2,2'-双嘧啶和顺式-[M(C6F5)2(THF)2] 反应,分别形成二核、三核和四核配合物 2、3 和 4,具体取决于试剂和金属的类型 (M = Pt, Pd)。配合物 1 与 KCN 反应形成阴离子双核配合物 [PPh3(CH3)]2[(C6F5)2Pt(μ-PPh2)2Pt(CN)2] (6)。配合物 6 作为顺式-[M(C6F5)2(THF)2] 或 1 的金属配体产生相应的六核或八核配合物 7、8 和 9。 [PPh3(CH3)]4[(C6F5) )2Pt(μ-PPh2)2Pt(μ-CN)2Pd(C6F5)2}2] (8) 已通过 X 射线衍射确定。(© Wiley-VCH Verlag GmbH & Co.
