Abstract
An X-ray crystal structure of the methylbenzodithiazolyl radical MeC6H3S2N, MBDTA, reveals that it forms a regularly spaced pi-stack motif in the soli d state; variable temperature magnetic studies show that the susceptibility passes through a broad maximum at 140 K indicative of exceptionally strong antiferromagnetic coupling for an organic radical possessing extended magn etic interactions. Its behaviour can be modelled as a two-dimensional Heise nberg square lattice of S = 1/2 ions with J = -72 K.
