The material structure described by La3SiCl3 crystallizes in the cubic I4_132 space group. La(1) is bonded to two equivalent Si(1) and four equivalent Cl(1) atoms to form a mixture of corner and edge-sharing LaSi2Cl4 octahedra. The corner-sharing octahedral tilt angles range from 2-3°. Si(1) is bonded to six equivalent La(1) atoms to form edge-sharing SiLa6 octahedra. Cl(1) is bonded in a rectangular see-saw-like geometry to four equivalent La(1) atoms. is represented by the CIF file [CIF]
