In organic chemistry, a cyclo[n]carbon (or simply cyclocarbon) is a chemical compound consisting solely of a number n of carbon atoms covalently linked in a ring. Since the compounds are composed only of carbon atoms, they are allotropes of carbon. Possible bonding patterns include all double bonds (a cyclic cumulene) or alternating single bonds and triple bonds (a cyclic polyyne). As of 2020, the only cyclocarbon that has been synthesized is cyclo[18]carbon. (en) Cyklokarbon (cyklo[18]karbon, cyklooktadekawęgiel, cyklo[18]węgiel) C18 – alotropowa odmiana węgla o strukturze cząsteczkowej (podobnie jak fuleren). Ma strukturę pierścienia złożonego z 18 atomów węgla, w którym naprzemiennie występują wiązania potrójne i pojedyncze. (pl) Um ciclo [n] carbono é um composto químico que consiste unicamente em um número n de átomos de carbono ligados em um anel por ligações duplas covalentes (um cumulênio cíclico). Como o composto é composto apenas por átomos de carbono, é considerado um alótropo exótico de carbono. Se n é mesmo existe uma estrutura alternativa onde as ligações alternam entre ligações simples e triplas (um poliacetileno cíclico). (pt) |
