Crystal structure of Au-pseudocarbyne(C₆).

ABSTRACT: Carbyne-related materials permit exploring the potentially extraordinary properties of this long-sought but still elusive carbon allotrope. However, accurate understanding of these materials is challenging. Here we report the crystal structure of a Au-pseudocarbyne, a representative of a possible new family of materials consisting of sp-hybridized carbon chains and stabilizing metal atoms. Au-pseudocarbyne(C₆), the representative pseudocarbyne containing six-membered carbon chains, has space group P6/mmm¹⁹¹ and unit-cell parameters a = b = 0.60 nm, c = 0.896 nm, α = β = 90°, γ = 120°. Its long-range structure can be understood as intimately intergrown bundles, each consisting of six parallel, infinite carbon chains surrounding a column of gold atoms. This compound, to
