Materials Data on Sr5Ta4O15 by Materials Project

Kristin Persson
Sr5Ta4O15 crystallizes in the trigonal P-3m1 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 nine equivalent O2- atoms. There are three shorter (2.54 Å) and six longer (2.93 Å) Sr–O bond lengths. In the second Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form distorted SrO12 cuboctahedra that share corners with nine equivalent SrO12 cuboctahedra, faces...
