TmInO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Tm(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. In(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing InO6 octahedra. The corner-sharing octahedral tilt angles range from 45-49°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Tm(1) and two equivalent In(1) atoms to form distorted corner-sharing OTm2In2 trigonal pyramids. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Tm(1) and two equivalent In(1) atoms.
TmInO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Tm(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. There is one shorter (2.20 Å) and one longer (2.29 Å) Tm(1)-O(1) bond length. There are two shorter (2.22 Å) and two longer (2.54 Å) Tm(1)-O(2) bond lengths. In(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing InO6 octahedra. The corner-sharing octahedral tilt angles range from 45-49°. Both In(1)-O(1) bond lengths are 2.28 Å. There are two shorter (2.14 Å) and two longer (2.17 Å) In(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Tm(1) and two equivalent In(1) atoms to form distorted corner-sharing OTm2In2 trigonal pyramids. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Tm(1) and two equivalent In(1) atoms.
