KMnCl3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 8-coordinate geometry to two equivalent Cl(2) and six equivalent Cl(1) atoms. Mn(1) is bonded to two equivalent Cl(2) and four equivalent Cl(1) atoms to form corner-sharing MnCl6 octahedra. The corner-sharing octahedral tilt angles range from 19-24°. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to three equivalent K(1) and two equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing ClK3Mn2 trigonal bipyramids. In the second Cl site, Cl(2) is bonded in a distorted see-saw-like geometry to two equivalent K(1) and two equivalent Mn(1) atoms.
KMnCl3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 8-coordinate geometry to two equivalent Cl(2) and six equivalent Cl(1) atoms. There is one shorter (3.17 Å) and one longer (3.19 Å) K(1)-Cl(2) bond length. There are a spread of K(1)-Cl(1) bond distances ranging from 3.16-3.40 Å. Mn(1) is bonded to two equivalent Cl(2) and four equivalent Cl(1) atoms to form corner-sharing MnCl6 octahedra. The corner-sharing octahedral tilt angles range from 19-24°. Both Mn(1)-Cl(2) bond lengths are 2.53 Å. All Mn(1)-Cl(1) bond lengths are 2.54 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to three equivalent K(1) and two equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing ClK3Mn2 trigonal bipyramids. In the second Cl site, Cl(2) is bonded in a distorted see-saw-like geometry to two equivalent K(1) and two equivalent Mn(1) atoms.
