Abstract
CaLaCuGaO5 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.33–2.98 Å. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.40–2.96 Å. Cu2+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with four equivalent CuO6 octahedra and corners with two GaO4 tetrahedra. The corner-sharing octahedra tilt angles range from 9–10°. There are a spread of Cu–O bond distances ranging from 1.93–2.48 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 CuO6 octahedra and corners with two equivalent GaO4 tetrahedra. The corner-sharing octahedral tilt angles are 39°. There are a spread of Ga–O bond distances ranging from 1.83–1.94 Å. In the second Ga3+ site, Ga3+ is bonded to four O2- atoms to form GaO4 tetrahedra that share corners with two equivalent CuO6 octahedra and corners with two equivalent GaO4 tetrahedra. The corner-sharing octahedral tilt angles are 39°. There are amore »
