Abstract

Sr5Ga6O14 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to six O2- atoms to form distorted SrO6 octahedra that share corners with six GaO4 tetrahedra and edges with two equivalent GaO4 tetrahedra. There are a spread of Sr–O bond distances ranging from 2.49–2.70 Å. In the second Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.50–3.06 Å. In the third Sr2+ site, Sr2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.37–3.01 Å. There are three inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to four O2- atoms to form GaO4 tetrahedra that share a cornercorner with one SrO6 octahedra and corners with four GaO4 tetrahedra. The corner-sharing octahedral tilt angles are 68°. There are a spread of Ga–O bond distances ranging from 1.86–1.89 Å. In the second Ga3+ site, Ga3+ is bonded to four O2- atoms to form GaO4 tetrahedra that share a cornercorner with one SrO6 octahedra and corners with threemore »« less
