Abstract

When trans,trans-(C₆F₅)(p-tol₃P) ₂Pt(C≡C)₃Pt-(P-p-tol₃)₂(C ₆F₅) and Ar₂P(CH₂) _mPAr₂ (m l Ar = 8 / p-tol, 10 / Ph, 11 / Ph, 12 / Ph, 14 / p-tol) are reacted, p-tol₃P is displaced to give products in which the diphosphines span the platinum end groups. One crystal structure (m = 14) shows a double-helical conformation in which the sp³ carbon chains twist around the sp chain, and others (m = 10, 11) show nonhelical conformations with lateral shielding of the sp chain.
