Mn Zn Sn Sn
MnZnSn2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MnZnSn2 clusters. Mn(1) is bonded in a water-like geometry to one Zn(1) and two equivalent Sn(1) atoms. The Mn(1)-Zn(1) bond length is 1.30 Å. Both Mn(1)-Sn(1) bond lengths are 0.80 Å. Zn(1) is bonded in a 3-coordinate geometry to one Mn(1) and two equivalent Sn(1) atoms. Both Zn(1)-Sn(1) bond lengths are 1.56 Å. Sn(1) is bonded in a single-bond geometry to one Mn(1) and one Zn(1) atom.
