Susceptibility and Mössbauer measurements have been made on a saturated FeCl 3 ‐ graphite intercalation compound with alternating graphite and FeCl 3 ,‐layers. It orders magnetically at 4 K. Extreme broadening of the Mössbauer spectrum is found in the critical region, and there is no anomaly in the sucseptibility. The moments lie in planes which are antiferromagnetic. Anisotropy of the susceptibility is ascribed t o the presence of Fez+ ions a t low temperatures, but a t room temperature there is rapid electron hopping between the iron sites.
