Abstract

Sm3GaO6 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. there are two inequivalent Sm3+ sites. In the first Sm3+ site, Sm3+ is bonded to seven O2- atoms to form distorted SmO7 pentagonal bipyramids that share corners with two equivalent SmO7 pentagonal bipyramids, a cornercorner with one GaO4 tetrahedra, edges with eight SmO7 pentagonal bipyramids, and an edgeedge with one GaO4 tetrahedra. There are a spread of Sm–O bond distances ranging from 2.34–2.52 Å. In the second Sm3+ site, Sm3+ is bonded to seven O2- atoms to form distorted SmO7 pentagonal bipyramids that share corners with five SmO7 pentagonal bipyramids, corners with three equivalent GaO4 tetrahedra, edges with five SmO7 pentagonal bipyramids, an edgeedge with one GaO4 tetrahedra, and a faceface with one SmO7 pentagonal bipyramid. There are a spread of Sm–O bond distances ranging from 2.28–2.67 Å. Ga3+ is bonded to four O2- atoms to form GaO4 tetrahedra that share corners with seven SmO7 pentagonal bipyramids and edges with three SmO7 pentagonal bipyramids. There is one shorter (1.86 Å) and three longer (1.89 Å) Ga–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to three Sm3+ and one Ga3+more »« less
