Materials Data on Mg(IO8)2 by Materials Project

Abstract

MgO6(O5I)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two magnesium;dihydroxide;tetrahydrate molecules and two O5I clusters. In each O5I cluster, there are five inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one I atom. The O–I bond length is 1.90 Å. In the second O site, O is bonded in a single-bond geometry to one I atom. The O–I bond length is 1.93 Å. In the third O site, O is bonded in a single-bond geometry to one I atom. The O–I bond length is 1.87 Å. In the fourth O site, O is bonded in a single-bond geometry to one I atom. The O–I bond length is 1.86 Å. In the fifth O site, O is bonded in a water-like geometry to two equivalent I atoms. There are one shorter (2.00 Å) and one longer (2.01 Å) O–I bond lengths. I is bonded to six O atoms to form edge-sharing IO6 octahedra.
