Abstract

The synthesis of rigid-rod organometallic polymers including the linear triplatinum units, {Pt₃(μ-dpmp)₂}, connected by π-conjugated bisisocyanides, was analyzed. With the increase of π-acidity of the terminal isocyanide, the Pt-Pt bond length is longer due to electron transfer from the Pt₃ core to the isocyanide group was observed. The structure of the compound was determined by X-ray crystallography, was composed of the linear, metal-metal bonded fragments covalently connected by the bisisocyanide molecules, which resulted in an infinite rigid-rod polymeric structure. The results show that organometallic polymer readily reacted with electrophiles such as H₊, tene, and electron-deficient alkynes.
