Abstract

Zn3In2O6 is Aluminum carbonitride-like structured and crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are four inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to five O2- atoms to form ZnO5 trigonal bipyramids that share corners with two ZnO4 tetrahedra, corners with two equivalent InO5 trigonal bipyramids, corners with four ZnO5 trigonal bipyramids, an edgeedge with one InO5 trigonal bipyramid, and edges with two ZnO5 trigonal bipyramids. There are a spread of Zn–O bond distances ranging from 1.95–2.46 Å. In the second Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with three InO6 octahedra, corners with four ZnO4 tetrahedra, a cornercorner with one InO5 trigonal bipyramid, and corners with two ZnO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 60–64°. There are two shorter (2.02 Å) and two longer (2.03 Å) Zn–O bond lengths. In the third Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with three InO6 octahedra, corners with four equivalent ZnO4 tetrahedra, a cornercorner with one InO5 trigonal bipyramid, and corners with two equivalent ZnO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 61–63°. There are a spread of Zn–O bond distances ranging from 2.01–2.03 Å. In the fourth Zn2+ site, Zn2+ is bonded to five O2- atoms to form distorted ZnO5 trigonal bipyramids that share corners with two equivalent ZnO4 tetrahedra, corners with two equivalent InO5 trigonal bipyramids, corners with four equivalent ZnO5 trigonal bipyramids, an edgeedge with one InO5 trigonal bipyramid, and edges with two equivalent ZnO5 trigonal bipyramids. There are a spread of Zn–O bond distances ranging from 1.94–2.48 Å. There are four inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with four ZnO4 tetrahedra and edges with six InO6 octahedra. There are four shorter (2.23 Å) and two longer (2.26 Å) In–O bond lengths. In the second In3+ site, In3+ is bonded to five O2- atoms to form InO5 trigonal bipyramids that share corners with three ZnO4 tetrahedra, corners with six ZnO5 trigonal bipyramids, and edges with three ZnO5 trigonal bipyramids. There are a spread of In–O bond distances ranging from 2.05–2.48 Å. In the third In3+ site, In3+ is bonded in a 4-coordinate geometry to five O2- atoms. There are a spread of In–O bond distances ranging from 2.09–2.79 Å. In the fourth In3+ site, In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with five ZnO4 tetrahedra and edges with six InO6 octahedra. There are a spread of In–O bond distances ranging from 2.23–2.27 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded to three Zn2+ and one In3+ atom to form OZn3In tetrahedra that share corners with nine OZnIn3 tetrahedra and corners with three OZn3In trigonal pyramids. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three Zn2+ and two In3+ atoms. In the third O2- site, O2- is bonded to four In3+ atoms to form distorted OIn4 tetrahedra that share corners with twelve OIn4 tetrahedra and edges with three OZnIn3 tetrahedra. In the fourth O2- site, O2- is bonded to one Zn2+ and three In3+ atoms to form distorted OZnIn3 tetrahedra that share corners with twelve OZn3In tetrahedra and edges with three OZnIn3 tetrahedra. In the fifth O2- site, O2- is bonded to three Zn2+ and one In3+ atom to form corner-sharing OZn3In tetrahedra. In the sixth O2- site, O2- is bonded to three Zn2+ and one In3+ atom to form a mixture of distorted corner and edge-sharing OZn3In trigonal pyramids. In the seventh O2- site, O2- is bonded to one Zn2+ and three In3+ atoms to form distorted OZnIn3 tetrahedra that share corners with twelve OZn3In tetrahedra and edges with three OIn4 tetrahedra. In the eighth O2- site, O2- is bonded to three Zn2+ and one In3+ atom to form corner-sharing OZn3In tetrahedra. In the ninth O2- site, O2- is bonded to three Zn2+ and one In3+ atom to form a mixture of distorted corner and edge-sharing OZn3In trigonal pyramids.
