In the dianion of the title salt, (C(14)H(12)N(2))[CuI(3)], the Cu(I) atom is coordinated by three I(-) ions that define a nearly trigonal-planar geometry; the Cu(I) atom lies 0.1407 (6) Å out of the plane. With the exception of the methyl-ene C atoms, the dication is essentially planar (r.m.s deviation = 0.067 Å). The most significant inter-action between the ions is a C-H⋯I contact.
