Neutron diffraction studies on powder samples of FeOCl and FeOCl(TTF)1/8.5 establish that TTF intercalated into FeOCl contributes to the diffraction pattern and exhibits long-range order. Room-temperature time-of-flight diffraction results are reported. The structure of FeOCl was refined in a space group Pmnm with a = 3.7730 (1) Å, b = 7.9096 (1) Å, and c = 3.3010 (1) Å. Least-squares Rietveld refinement (21 parameters, 3296 degrees of freedom) yielded R = 0.0169, Rw = 0.0248 (Rexpected = 0.0115). The structure of FeOCl(TTF)1/8.5 was refined in space group Immm with a = 3.784 (2) Å, b = 3.341 (2) Å, and c = 25.97 (2) Å, using a model in which the TTF molecules lie in the bc plane, with equal occupancy of the four possible sites, to give R = 0.0203, Rw = 0.0289, and Rexpected = 0.0111 (28 parameters, 1894 degrees of freedom).
