Mn Mn Mn Cr Sn
CrMn3Sn is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Cr(1) is bonded to twelve equivalent Mn(1) atoms to form CrMn12 cuboctahedra that share corners with twelve equivalent Cr(1)Mn12 cuboctahedra, faces with six equivalent Cr(1)Mn12 cuboctahedra, and faces with eight equivalent Sn(1)Mn6 octahedra. All Cr(1)-Mn(1) bond lengths are 3.54 Å. Mn(1) is bonded in a linear geometry to four equivalent Cr(1) and two equivalent Sn(1) atoms. Both Mn(1)-Sn(1) bond lengths are 2.50 Å. Sn(1) is bonded to six equivalent Mn(1) atoms to form SnMn6 octahedra that share corners with six equivalent Sn(1)Mn6 octahedra and faces with eight equivalent Cr(1)Mn12 cuboctahedra. The corner-sharing octahedra are not tilted.
