The magnetic property of the title radical crystals was analyzed by the Bleaney-Bowers equation with <I>J</I>/<I>k</I><SUB>B</SUB> = +8.85 K, which is consistent with the dimetic molecular arrangement with "pseudo-<I>ortho</I>" stacking determined by crystallographic analysis. The inter-dimer interaction was antiferromagnetic.
