Synthetic pyrrhotites Fe1-xS, synthesized at various compositions and temperatures, show the presence of two new superstructures based on the hexagonal subcell of the NiAs type (axes A and C): one, in the range 1-x=0.89 to 0.93, has a = 90A and c = 3C; the other, in the range 1 -x = 0.935 to 0.975, has a = 2A but c irrationally related to C, varying with composition.
