The crystal structure of Sr_2Nb_2O_7 comprises slabs with a perovskite-type structure that are separated by planes of additional O atoms. The driving force for the modulation is shown to be internal strain around the Sr atoms that lie at the interface between the slabs. At room temperature, Sr_2Nb_2O_7 crystallizes in the superspace group Cmc2_1(\\alpha00)0s0, with lattice parameters a = 3.9544\\,(7), b = 26.767\\,(6) and c = 5.6961\\,(8)\\AA. The modulation wave vector is determined as q = 0.488\\,(3)\\,a^*. X-ray diffraction data were collected at a synchrotron using a CCD area detector. A total of 3626 unique main reflections and 1262 unique first-order satellites with I \\,\\,3 (I\\,) were obtained. Refinements using a single harmonic modulation wave converged at R = 0.057 (R = 0.051 for the main reflections and R = 0.121 for the satellite reflections). The modulated structure is interpreted in terms of rotations of NbO_6 octahedra and displacements of the Sr atoms.","annote":"","author":[{"family":"Daniels","given":"Peter"},{"family":"Tamazyan","given":"Rafael"},{"family":"Kuntscher","given":"Christine A."},{"family":"Dressel","given":"Martin"},{"family":"Lichtenberg","given":"Frank"},{"family":"van Smaalen","given":"Sander"}],"citation-label":"Daniels:ck0015","collection-editor":[],"collection-title":"","container-author":[],"container-title":"Acta Crystallographica Section B","documents":[],"edition":"","editor":[],"event-date":{"date-parts":[["2002","dec"]],"literal":"2002"},"event-place":"","id":"6328c8cb297648c86ef8f0b4d084e498ulrikeoffenbeck","interhash":"e1650cd24c86b7f586e99aaa83b26a1a","intrahash":"6328c8cb297648c86ef8f0b4d084e498","issue":"6","issued":{"date-parts":[["2002","dec"]],"literal":"2002"},"keyword":"modulation structure","misc":{"doi":"10.1107/S010876810201741X"},"note":"","number":"6","number-of-pages":"6","page":"970-976","page-first":"970","publisher":"","publisher-place":"","status":"","title":"The incommensurate modulation of the structure of Sr2Nb2O7","type":"article-journal","username":"ulrikeoffenbeck","version":"","volume":"58"},"44e1e8ce83a2a014e2bd53ee993e8055markusayasse":{"DOI":"10.1109/GROUP4.2017.8082171","ISBN":"","ISSN":"","URL":"","abstract":"","annote":"","author":[{"family":"Koerner","given":"R."},{"family":"Fischer","given":"I.
