In the dianion of the title salt, (C14H12N2)[CuI3], the CuI atom is coordinated by three I− ions that define a nearly trigonal-planar geometry; the CuI atom lies 0.1407 (6) Å out of the plane. With the exception of the methylene C atoms, the dication is essentially planar (r.m.s deviation = 0.067 Å). The most significant interaction between the ions is a C—H⋯I contact.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
