Materials Data on MgSiH12(OF)6 by Materials Project

Abstract

Mg(H2O)6SiF6 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two magnesium;hexahydrate molecules and two SiF6 clusters. In each SiF6 cluster, Si4+ is bonded in an octahedral geometry to six F1- atoms. There is two shorter (1.72 Å) and four longer (1.73 Å) Si–F bond length. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Si4+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Si4+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Si4+ atom.
