Mn Cr Cr Sn
Cr2MnSn crystallizes in the monoclinic Cm space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 5-coordinate geometry to one Cr(2) and four equivalent Mn(1) atoms. The Cr(1)-Cr(2) bond length is 2.66 Å. There are a spread of Cr(1)-Mn(1) bond distances ranging from 2.61-2.76 Å. In the second Cr site, Cr(2) is bonded in a 5-coordinate geometry to one Cr(1) and four equivalent Sn(1) atoms. There are a spread of Cr(2)-Sn(1) bond distances ranging from 2.66-2.81 Å. Mn(1) is bonded in a single-bond geometry to four equivalent Cr(1) and one Sn(1) atom. The Mn(1)-Sn(1) bond length is 0.08 Å. Sn(1) is bonded in a single-bond geometry to four equivalent Cr(2) and one Mn(1) atom.
