Abstract

Reactions of trans,trans-(C₆F₅)(p-tol ₃P)₂Pt(C≡C)_nPt(P-p-tol₃) ₂(C₆F₅) (n = 3, 4) and Ph₂P(CH ₂)₃PPh₂ (2.5 equiv) give the tetraplatinum complexes trans,trans, trans,trans-(C₆F ₅)Pt(C≡C)_nPt(C₆F₅)(PPh ₂(CH₂)₃Ph₂P)₂-(C ₆F₅)Pt(C≡C)_nPt(C₆F ₅)(PPh₂(CH₂)₃Ph₂P) ₂ (95-81%), in which two sp carbon chains span two 12-membered-ring termini. Chain-chain interactions have been probed by crystallography, UV-visible spectroscopy, cyclic voltammetry, and thermolyses.
