ABSTRACT
The dithiadiazolyl radical p-NCC6F4C6F4CNSSN• (4) retains its monomericnature in the solid state with molecules linked together into chains via supramolecularCN···S interactions. Variable temperature magnetic studies on 4 show that it behaves as anear-ideal Curie paramagnet (|θ| less than 0.1 K), indicating negligible intermolecularexchange. The effective magnetic moment (1.78 μB) is temperature independent and inexcellent agreement with the value expected for an S = 1⁄2 paramagnet with g = 2.01(1.74μB). The lack of exchange coupling between radicals is attributed to the absence ofsignificant orbital overlap between radical centres.
