Synthesis and characterization of [NBu4][Pt3(µ-PPh2)2(C6F5)5]: an anionic cluster containing an unusual µ3-PPh2 bridging system
Abstract
[NBu4]2[Pt2(µ-PPh2)2(C6F5)4] reacts with cis-[Pt(C6F5)2(thf)2](1:2 molar ratio) yielding [NBu4][Pt3(µ-PPh2)2(C6F5)5] which contains unusual µ3-PPh(1,2-η2-Ph)-κ3P phosphido and semi-bridging C6F5 ligands and two Pt–Pt bonds of length 2.899(1) and 2.772(1)Å.
