A hydrocarbon existing uniquely in solution: a heterolytically dissociative hydrocarbon that produces the corresponding hydrocarbon salt by crystallization

Abstract

A covalent hydrocarbon (R₄–R₁), formed in chloroform or the other aprotic solvents by cation–anion co-ordination of the tricyclopropylcyclopropenylium ion (R₄⁺) and the tris(7H-dibenzo[c,g]fluorenemethyl)methide ion (R₁^–), can not be isolated in the solid state, but is converted into the corresponding hydrocarbon salt (R₄⁺R₁^–) at the moment of crystallization by evaporation or refrigeration of the solutions.
