Materials Data on Sr3NbGa3(SiO7)2 by Materials Project
Abstract
Sr3NbGa3Si2O14 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Sr–O bond distances ranging from 2.56–2.76 Å. In the second Sr2+ site, Sr2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Sr–O bond distances ranging from 2.55–2.72 Å. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with six GaO4 tetrahedra. All Nb–O bond lengths are 2.03 Å. There are two inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to four O2- atoms to form GaO4 tetrahedra that share corners with two equivalent NbO6 octahedra and corners with two equivalent SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 57°. All Ga–O bond lengths are 1.86 Å. In the second Ga3+ site, Ga3+ is bonded to four O2- atoms to form GaO4 tetrahedra that share corners with two equivalent NbO6 octahedra and corners with two equivalent SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 58°. All Ga–O bond lengths are 1.86 Å. Si4+ is bonded to fourmore »
