As other GR compounds, it is unstable with respect to the action of oxygen and oxidises later on. Its chemical composition was determined to be [FeII6 FeIII2(OH)16]2+[C2O42- · nH2O], with n more likely equal to 3 on the basis of structural considerations. The composition does not vary and the Fe (II) / Fe (III) ratio in the compound is measured by means of transmission Mössbauer spectroscopy at 78 K and 20 K in the range from 2.8 to 3.2 for various samples at various stages of the reaction. GR(C2O42-) is paramagnetic at both temperatures and is unambiguously distinguished from ferrous hydroxide, the initial reactant, and magnetite, the main final product, which are magnetically ordered at 20 K. The spectrum of the GR compound is composed of three quadrupole doublets, one due to the Fe(III) cations characterised by a small quadrupole splitting ΔEQ of 0.40 mm s−1, and two due to the Fe(II) cations, characterised by larger ΔEQ values of about 2.55 and 2.85 mm s−1. Finally, from the observed equilibrium conditions between ferrous hydroxide and GR(C2O42-), the standard free enthalpy of formation of GR(C2O42-) was computed to be : ΔG°f[FeII6 FeIII2 (OH)16]2+[C2O42- · 3H2O] = −5383 ± 3 kJ mol−1.</div>","PeriodicalId":100507,"journal":{"name":"European Journal of Solid State and Inorganic Chemistry","volume":"35 10","pages":"Pages 655-666"},"PeriodicalIF":0.0,"publicationDate":"1998-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0992-4361(99)80006-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75264723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
