MnSi3Te is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Mn(1) is bonded in a 3-coordinate geometry to three equivalent Si(1) atoms. All Mn(1)-Si(1) bond lengths are 3.29 Å. Si(1) is bonded in a 3-coordinate geometry to one Mn(1) and two equivalent Te(1) atoms. There is one shorter (2.32 Å) and one longer (2.76 Å) Si(1)-Te(1) bond length. Te(1) is bonded to six equivalent Si(1) atoms to form corner-sharing TeSi6 octahedra. The corner-sharing octahedra are not tilted.
