The three-solvent reaction of (Bu(4)N)(2)[Zn(dmt)(2)] (dmt = C3S52- =
3-thioxo-1,2-dithiole-4,5-dithiolato) (CH2-Cl2), (Et(4)N)(2)tto (tto =
C2S42- = tetrathiooxalate) (H2O), and CuCl2 . 2H(2)O (CH3OH) yields t
he anionic tetrameric copper complex (Bu(4)N)(2)[Cu(dmt)](4). The dian
ion contains a planar, eight-membered ring core of four Cu atoms and f
our S atoms. The dmt ligand coordinates for the first time in this par
ticular fashion.
