The crystal structure of Sr 3 Fe 2 O 7Ϫd with iron in the average oxidation state ϩ 4 has been studied by time-of-flight neutron powder diffraction. The diffraction data were collected at more than 30 points between 18 and 300 K. A slight anomalous behavior in lattice parameters was observed at aro
