Abstract
The [Cr-2(azin)(4)Cl-2](2-) ion has been made and structurally characterize d. Despite the long Cr-Cr distance (2.688(2) Angstrom), there is strong cou pling of all electron spins, presumably by superexchange via the bridging s pins, presumably by superexchange via the azin ligands (azin = anion of 7-a zaindole).
