This compound presents a two-step spin transition with relatively abrupt steps centred at ca. 170 K and 145 K and a plateau at around 155 K. The origin of the two-step transition is discussed in light of these structural studies. The observations are compatible with a mostly disordered state between the two steps, consisting of mixing of high-spin and low-spin species, while weak substructure reflections in the mixed phase could indicate some degree of long-range order of the high-spin and low-spin sites. info:eu-repo/grantAgreement/ES/DGA/E11-17R info:eu-repo/grantAgreement/ES/MICINN/MAT2017-86019-R info:eu-repo/grantAgreement/ES/MINECO/MAT2015-68200-C2-2-P info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.404 2019 CRYSTALLOGRAPHY 10 / 26 = 0.385 2019 Q2 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 165 / 314 = 0.525 2019 Q3 T2 0.594 2019 Chemical Engineering (miscellaneous) 2019 Q2 Materials Science (miscellaneous) 2019 Q2 Inorganic Chemistry 2019 Q2 Condensed Matter Physics 2019 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Kitase, Kosuke (orcid)0000-0003-3567-7030 Palacios, Elías Universidad de Zaragoza (orcid)0000-0002-9687-4903 Castro, Miguel Universidad de Zaragoza Fernández-Blanco, Ángel (orcid)0000-0003-2962-9251 Burriel, Ramón Universidad de Zaragoza Kitazawa, Takafumi 2003 395 Universidad de Zaragoza Dpto.
