Crystal structures and magnetic properties of a sterically encumbered dithiadiazolyl radical, 2,4,6-(F3C)3C6H2CNSSN˙
Abstract
The sterically protected dithiadiazolyl radical (F3C)3C6H2CNSSN˙ (1) crystallises in two polymorphs: 1α, comprised of monomeric units and 1β, containing a mixture of both π*–π* dimers and S = ½ monomers; whilst both polymorphs exhibit similar structure-directing motifs, the variation in packing leads to different magnetic behaviour.
