KMnCl3 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 8-coordinate geometry to one Cl(1), three equivalent Cl(2), and four equivalent Cl(3) atoms. Mn(1) is bonded to one Cl(3), two equivalent Cl(2), and three equivalent Cl(1) atoms to form edge-sharing MnCl6 octahedra. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 4-coordinate geometry to one K(1) and three equivalent Mn(1) atoms. In the second Cl site, Cl(2) is bonded in a 5-coordinate geometry to three equivalent K(1) and two equivalent Mn(1) atoms. In the third Cl site, Cl(3) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Mn(1) atom.
KMnCl3 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 8-coordinate geometry to one Cl(1), three equivalent Cl(2), and four equivalent Cl(3) atoms. The K(1)-Cl(1) bond length is 3.31 Å. There are two shorter (3.25 Å) and one longer (3.33 Å) K(1)-Cl(2) bond length. All K(1)-Cl(3) bond lengths are 3.19 Å. Mn(1) is bonded to one Cl(3), two equivalent Cl(2), and three equivalent Cl(1) atoms to form edge-sharing MnCl6 octahedra. The Mn(1)-Cl(3) bond length is 2.42 Å. Both Mn(1)-Cl(2) bond lengths are 2.56 Å. There is one shorter (2.56 Å) and two longer (2.62 Å) Mn(1)-Cl(1) bond lengths. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 4-coordinate geometry to one K(1) and three equivalent Mn(1) atoms.
