Abstract
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) Å, b= 12.2768(12) Å, c = 14.0265(14) Å, α = 98.987(2)°, β = 97.972(2)°, γ = 110.402(2)°, V = 1732.2(3) Å3, 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.
