Formation of a heterobimetallic cyclohexa-1,4-dienyl-hydrido-complex from an acetylide and buta-1,3-diene: crystal structure of [(p-MeC6H4CC)Pt(µ-dppm)2-(µ-H)Ir(CO){CC(C6H3Me)CH2CHCHCH2}][BF4](dppm = Ph2PCH2PPh2)

Abstract

[(p-MeC₆H₄CC)₂Pt(µ-dppm)₂Ir(CO)][BF₄](dppm = Ph₂PCH₂PPh₂) reacts with buta-1,3-diene to give the title compound in which a p-tolylacetylide ligand from platinum and a buta-1,3-diene on iridium have combined together to give the novel ligand in the title compound; isoprene and 1,1,4,4-tetradeuteriobuta-1,3-diene react similarly.
