The title salt, bis[2,3-bis(aminocarbonyl)-8,9-bis(methylsulfanyl)tetrathiafulvalenium] di-![[mu]](/logos/entities/mu_rmgif.gif)
-bromido-bis[bromidocopper(II)], (C10H10N2O2S6)2[Cu2Br4], contains 2,3-bis(aminocarbonyl)-8,9-bis(methylsulfanyl)tetrathiafulvalenium radical cations, [DMT-TTF(CONH2)2]·+, and [Cu2Br4]2- anions. The cations are associated across centres of inversion in a head-to-tail fashion via short face-to-face S
S stacking (TTF moiety). These dimers are further assembled into a one-dimensional chain structure via interdimer double SS contacts involving the methylsulfanyl groups. The one-dimensional chains give rise to a two-dimensional structure through intermolecular double N-HO hydrogen bonds involving the amide group. The [Cu2Br4]2- anions, which straddle centres of inversion, are located between the cation layers. Electron paramagnetic resonance measurements show a radical signal, indicating that the two TTF·+ radicals are not completely coupled in the dimer.
