Abstract
CuAlO3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Cu3+ sites. In the first Cu3+ site, Cu3+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with six CuO6 octahedra, corners with four AlO6 pentagonal pyramids, and edges with four AlO6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 56–58°. There are a spread of Cu–O bond distances ranging from 1.90–2.45 Å. In the second Cu3+ site, Cu3+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with six CuO6 octahedra, corners with four AlO6 pentagonal pyramids, and edges with four AlO6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 56–58°. There are four shorter (1.91 Å) and two longer (2.47 Å) Cu–O bond lengths. In the third Cu3+ site, Cu3+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with six CuO6 octahedra, corners with four AlO6 pentagonal pyramids, and edges with four AlO6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 56–58°. There are four shorter (1.91 Å) and two longer (2.46 Å) Cu–O bond lengths. In the fourth Cu3+ site, Cu3+ ismore »

In the second O2- site, O2- is bonded to two Cu3+ and two Al3+ atoms to form a mixture of edge and corner-sharing OAl2Cu2 tetrahedra. In the third O2- site, O2- is bonded to two Cu3+ and two Al3+ atoms to form a mixture of edge and corner-sharing OAl2Cu2 tetrahedra. In the fourth O2- site, O2- is bonded to two Cu3+ and two Al3+ atoms to form a mixture of edge and corner-sharing OAl2Cu2 tetrahedra. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to two Cu3+ and two Al3+ atoms. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two Cu3+ and two Al3+ atoms.},
