Mn Mn Ge Cl
Mn2GeCl crystallizes in the monoclinic Cm space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 5-coordinate geometry to one Mn(2), four equivalent Ge(1), and four equivalent Cl(1) atoms. The Mn(1)-Mn(2) bond length is 2.11 Å. There are a spread of Mn(1)-Ge(1) bond distances ranging from 3.26-3.34 Å. There are a spread of Mn(1)-Cl(1) bond distances ranging from 2.58-2.67 Å. In the second Mn site, Mn(2) is bonded in a 4-coordinate geometry to one Mn(1), four equivalent Ge(1), and four equivalent Cl(1) atoms. There are a spread of Mn(2)-Ge(1) bond distances ranging from 3.26-3.34 Å. There are a spread of Mn(2)-Cl(1) bond distances ranging from 2.16-2.27 Å. Ge(1) is bonded to four equivalent Mn(1), four equivalent Mn(2), and four equivalent Ge(1) atoms to form a mixture of distorted face and corner-sharing GeMn8Ge4 cuboctahedra. All Ge(1)-Ge(1) bond lengths are 3.03 Å. Cl(1) is bonded in a 8-coordinate geometry to four equivalent Mn(1) and four equivalent Mn(2) atoms.
