Abstract

GdSrCoO4 is (La,Ba)CuO4-derived structured and crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.40–2.70 Å. Gd3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Gd–O bond distances ranging from 2.32–2.69 Å. Co3+ is bonded to six O2- atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles are 12°. There are a spread of Co–O bond distances ranging from 1.90–2.02 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to one Sr2+, four equivalent Gd3+, and one Co3+ atom to form a mixture of distorted edge and corner-sharing OSrGd4Co octahedra. The corner-sharing octahedra tilt angles range from 0–11°. In the second O2- site, O2- is bonded to four equivalent Sr2+, one Gd3+, and one Co3+ atom to form a mixture of distorted edge and corner-sharing OSr4GdCo octahedra. The corner-sharing octahedra tilt angles range from 0–15°. In the third O2- site, O2- is bonded in a 6-coordinate geometry to two equivalent Sr2+, two equivalent Gd3+, and two equivalent Co3+ atoms.
