Abstract
- Magnetization, heat capacity, and neutron diffraction experiments on the \ensuremath{\beta}-phase of the dithiadiazolyl radical, p-NC.${\mathrm{C}}_{6}$${\mathrm{F}}_{4}$.CNSSN., provide conclusive evidence that this system exhibits noncollinear antiferromagnetism at 35.5 K, an unprecedented temperature for an organic radical. On the basis of magnetization and powder neutron diffraction results, coupled with theoretical calculations of the spin distribution within the molecule, a magnetic structure for this compound is proposed in which the interactions propagate through $\mathrm{S}\dots{}\mathrm{N}$ contacts.
