CaPrO3 is Ilmenite-like structured and crystallizes in the orthorhombic Pnma space group. Ca(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Pr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing PrO6 octahedra. The corner-sharing octahedral tilt angles range from 46-59°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a see-saw-like geometry to two equivalent Ca(1) and two equivalent Pr(1) atoms. In the second O site, O(2) is bonded to two equivalent Ca(1) and two equivalent Pr(1) atoms to form a mixture of distorted corner and edge-sharing OCa2Pr2 trigonal pyramids.
CaPrO3 is Ilmenite-like structured and crystallizes in the orthorhombic Pnma space group. Ca(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. There is one shorter (2.37 Å) and one longer (2.44 Å) Ca(1)-O(1) bond length. There are two shorter (2.34 Å) and two longer (2.68 Å) Ca(1)-O(2) bond lengths. Pr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing PrO6 octahedra. The corner-sharing octahedral tilt angles range from 46-59°. Both Pr(1)-O(1) bond lengths are 2.42 Å. There are two shorter (2.38 Å) and two longer (2.39 Å) Pr(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a see-saw-like geometry to two equivalent Ca(1) and two equivalent Pr(1) atoms. In the second O site, O(2) is bonded to two equivalent Ca(1) and two equivalent Pr(1) atoms to form a mixture of distorted corner and edge-sharing OCa2Pr2 trigonal pyramids.
