Abstract: In the title complex, (C₈H₂₀N)₂[Cu(C₃S₅)₂], each Cu atom is tetracoordinated by four dmit S atoms (dmit is 2-thioxo-1,3-dithiole-4,5-dithiolate), forming a slightly distorted square-planar arrangement. The average Cu-S bond length is a little larger than the sum of the single-bond covalent radii. The S-Cu-S bond angles for the vicinal S atoms are somewhat larger than the typical right angle and the other two angles are much smaller than 180°. The [Cu(dmit)₂]^2- anions and tetraethylammonium counter-cations form a layered arrangement in the crystal structure.
