Mono- and di-nuclear platinum σ-acetylide complexes of tetraethynylethene

Syntheses and X-ray structural characterizations of two types of platinum σ-acetylide complexes in which the metals are bound to tetraethynylethene skeletons are reported; these complexes are closely related to the basic constituents of a metal-linked carbon network and are prepared to explore the feasibility of thermodynamically controlled metal-acetylenic self assembly.
