Mn Mn Cl Cl
MnCl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MnCl cluster. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a distorted single-bond geometry to one Cl(1) atom. The Mn(1)-Cl(1) bond length is 1.12 Å. In the second Mn site, Mn(2) is bonded in a 2-coordinate geometry to one Cl(1) and one Cl(2) atom. The Mn(2)-Cl(1) bond length is 1.27 Å. The Mn(2)-Cl(2) bond length is 0.49 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 2-coordinate geometry to one Mn(1) and one Mn(2) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Mn(2) atom.
