Cs Mn Mn Mn Pb
CsMn3Pb is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Cs(1) is bonded to twelve equivalent Mn(1) atoms to form CsMn12 cuboctahedra that share corners with twelve equivalent Cs(1)Mn12 cuboctahedra, faces with six equivalent Cs(1)Mn12 cuboctahedra, and faces with eight equivalent Pb(1)Mn6 octahedra. There are a spread of Cs(1)-Mn(1) bond distances ranging from 3.36-3.79 Å. Mn(1) is bonded in a distorted linear geometry to four equivalent Cs(1) and two equivalent Pb(1) atoms. There is one shorter (2.38 Å) and one longer (2.68 Å) Mn(1)-Pb(1) bond length. Pb(1) is bonded to six equivalent Mn(1) atoms to form PbMn6 octahedra that share corners with six equivalent Pb(1)Mn6 octahedra and faces with eight equivalent Cs(1)Mn12 cuboctahedra. The corner-sharing octahedra are not tilted.
