[PtCl2(PPh3)2]与B10H12-0在异丙醇中回流反应,得到3个巢式十一顶铂十硼烷簇合物:[(PPh3)2PtB10H11-9-O-i-Pr](1),[(PPh3)2PtB10H10-8,10-(O-i-Pr)2](2)和[(PPh3)2PtB10H11-8-O-i-Pr](3).簇合物1~3都具有PtB10多面体骨架结构,其中Pt原子位于敞开的PtB4面上,且与4个B原子成键,每个Pt原子还与2个PPh3基团中的P原子成键.将溶剂热合成的方法引入到硼簇合物的合成中并进行同一反应,得到2个B10H21-0降解的巢式十一顶双铂九硼烷簇合物:[(PPh3)2(μ-PPh2)Pt2B9H6-3,9,11-(O-i-Pr)3](4)和[(PPh3)2(μ-PPh2)Pt2B9H6-3,9-(O-i-Pr)2-11-Cl](5).簇合物4和5都具有Pt2B9多面体骨架结构,2个Pt原子位于敞开的Pt2B3面上的相邻位置,且由一个PPh2基团桥连,每个Pt原子还与3个B原子和一个PPh3基团中的P原子成键.通过红外光谱、元素分析、X射线单晶衍射对5个簇合物进行了结构表征.
[PtCl2 (PPh3) 2] was refluxed with B10H12-0 in isopropanol to give three nested eleven platinum-decaborane clusters: [(PPh3) 2PtB10H11-9-Oi-Pr] , [(PPh3) 2PtB10H10-8,10- (Oi-Pr) 2] (2) and [(PPh3) 2PtB10H11-8-Oi-Pr] , In which the Pt atom is located on the open PtB4 surface and bonds with four B atoms and each Pt atom also bonds with P atoms in two PPh3 groups.The method of solvothermal synthesis is introduced into the boron cluster , Two B10H21-0-degraded nested eleven-dipalmito-borane clusters were obtained by the same reaction: [(PPh3) 2 (μ-PPh2) Pt2B9H6-3,9,11- (Oi -Pr) 3] (4) and [(PPh3) 2 (μ-PPh2) Pt2B9H6-3,9- (Oi-Pr) 2-11- Cl] Framework structure in which two Pt atoms are located adjacent to the open Pt2B3 plane and are bridged by one PPh2 group and each Pt atom is also bonded to P atoms in three B atoms and one PPh3 group via Five clusters were characterized by FTIR, elemental analysis and X-ray single crystal diffraction.
