资源简介：
Pr2CoO4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Pr3+ is bonded in a 1-coordinate geometry to nine O2- atoms. There are a spread of Pr–O bond distances ranging from 2.31–2.80 Å. Co2+ is bonded to six O2- atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (1.94 Å) and two longer (2.28 Å) Co–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Pr3+ and two equivalent Co2+ atoms to form a mixture of distorted corner, edge, and face-sharing OPr4Co2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded in a 6-coordinate geometry to five equivalent Pr3+ and one Co2+ atom.
