Materials Data on Sr7(H6Cl)2 by Materials Project
Abstract
Sr7(H6Cl)2 crystallizes in the hexagonal P-6 space group. The structure is three-dimensional. there are three inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to seven H1- and two equivalent Cl1- atoms. There are a spread of Sr–H bond distances ranging from 2.47–2.60 Å. Both Sr–Cl bond lengths are 3.16 Å. In the second Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to seven H1- and two equivalent Cl1- atoms. There are a spread of Sr–H bond distances ranging from 2.42–2.81 Å. Both Sr–Cl bond lengths are 3.12 Å. In the third Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine H1- atoms. There are three shorter (2.40 Å) and six longer (2.72 Å) Sr–H bond lengths. There are four inequivalent H1- sites. In the first H1- site, H1- is bonded to five Sr2+ atoms to form distorted HSr5 square pyramids that share corners with four ClSr6 pentagonal pyramids, corners with four equivalent HSr5 square pyramids, corners with eight HSr4 tetrahedra, an edgeedge with one ClSr6 pentagonal pyramid, edges with four equivalent HSr5 square pyramids, and edges with seven HSr4 tetrahedra. In the second H1- site, H1- is bonded to fourmore »
