A new salt (EV)(2) [Cu(mnt)(2)] [EV=tris(p-(diethylamino)phenyl)methylium; mnt=bis(1,2-dicyanovinylene-1,2-dithiolato)] was prepared by the reaction of [NBU4](2)[Cu(mnt)(2)] with ethyl violet dye (EV)CL. The crystallographic data are: triclinic P-1, a=11.1102(11)Angstrom, b=12.2768(12) Angstrom, c=14.0265(14) Angstrom, alpha=98.987(2)degrees, beta=97.972(2)degrees, gamma=110.402(2)degrees, V=1732.2(3) Angstrom(3), Z=1. The [Cu(mnt)(2)] dianion exhibits a quasi-square planar structure and the EV cation has a trigonal planar geometry with an A symmetric propeller-like conformation. A pseudo-dimmer of the EV cation and weak hydrogen bonds between the cation and the anion were observed in the crystal.
