}} Einsteinium triiodide is an iodide of the synthetic actinide einsteinium which has the molecular formula EsI3. This crystalline salt is an amber-coloured solid.〔Arnold F. Holleman, Nils Wiberg: ''Lehrbuch der Anorganischen Chemie'', 102nd Edition, de Gruyter, Berlin 2007, ISBN 978-3-11-017770-1, p. 1969.〕 It glows red in the dark due to einsteinium's intense radioactivity. It crystallises in the hexagonal crystal system in the space group ''R'' with the lattice parameters ''a'' = 753 pm and ''c'' = 2084.5 pm with six formula units per unit cell. Its crystal structure is isotypic with that of bismuth(III) iodide.〔R. G. Haire, ORNL Report 5485, 1978.〕〔J. R. Peterson: "Chemical Properties of Einsteinium: Part II", in: G. T. Seaborg (ed.): ''(Proceedings of the 'Symposium Commemorating the 25th Anniversary of Elements 99 and 100' )'', 23. January 1978; Report LBL-7701, April 1979, pp. 55–64.〕 ==References==
