the target complex trans,trans‐[(C6F5)(p‐tol3P)(Me2PhP)Pt(C≡C)Pt(PPhMe2)(Pp‐tol3)(C6F5)] (4, 2.3 %) as well as trans,trans‐[(C6F5)(Me2PhP)2Pt(C≡C)Pt(PPhMe2)(Pp‐tol3)(C6F5)] (5, 5.6 %). The crystal structures of 2, 4, and 5 were determined. The last two show much congestion about the PtC≡CPt linkage, and various geometrical features have been analyzed. Low‐temperature 1H NMR spectra of 4 were recorded
