Synopsis Diselenadiazolyls exhibit a stronger tendency to dimerize in the solid state than their corresponding dithiadiazolyl (DTDA) radicals, reflected in a range of dimerization modes for (p-XC6F4CNSeSeN)2, which contrast with those of the monomeric DTDA radicals, p-XC6F4CNSSN. The structure of (p-NCC6F4CNSeSeN)2 reflects a buildup of molecular strain in order to accommodate both dimerization and structure-directing CN···Se contacts, whereas the suppression of dimerization releases molecular strain yet retains structure-directing CN···S contacts for the corresponding DTDA radical.
