CsMnGa3 is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Cs(1) is bonded to twelve equivalent Ga(1) atoms to form CsGa12 cuboctahedra that share corners with twelve equivalent Cs(1)Ga12 cuboctahedra, faces with six equivalent Cs(1)Ga12 cuboctahedra, and faces with eight equivalent Mn(1)Ga6 octahedra. There are a spread of Cs(1)-Ga(1) bond distances ranging from 3.18-3.77 Å. Mn(1) is bonded to six equivalent Ga(1) atoms to form MnGa6 octahedra that share corners with six equivalent Mn(1)Ga6 octahedra and faces with eight equivalent Cs(1)Ga12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three shorter (2.25 Å) and three longer (2.66 Å) Mn(1)-Ga(1) bond lengths. Ga(1) is bonded in a 6-coordinate geometry to four equivalent Cs(1) and two equivalent Mn(1) atoms.
