K Mn Mn Cl
KMn2Cl crystallizes in the triclinic P1 space group. K(1) is bonded in a 4-coordinate geometry to one Mn(2), two equivalent Mn(1), and one Cl(1) atom. The K(1)-Mn(2) bond length is 2.92 Å. There is one shorter (1.85 Å) and one longer (1.95 Å) K(1)-Mn(1) bond length. The K(1)-Cl(1) bond length is 2.68 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 2-coordinate geometry to two equivalent K(1) and one Cl(1) atom. The Mn(1)-Cl(1) bond length is 2.79 Å. In the second Mn site, Mn(2) is bonded in a distorted single-bond geometry to one K(1) and two equivalent Cl(1) atoms. There is one shorter (1.97 Å) and one longer (3.06 Å) Mn(2)-Cl(1) bond length. Cl(1) is bonded in a 4-coordinate geometry to one K(1), one Mn(1), and two equivalent Mn(2) atoms.
