The crystal structure described by La3PI3 is Corundum-derived structured and crystallizes in the cubic I4_132 space group. La(1) is bonded to two equivalent P(1) and four equivalent I(1) atoms to form a mixture of corner and edge-sharing LaP2I4 octahedra. The corner-sharing octahedral tilt angles range from 6-11°. P(1) is bonded to six equivalent La(1) atoms to form edge-sharing PLa6 octahedra. I(1) is bonded in a rectangular see-saw-like geometry to four equivalent La(1) atoms. is represented by the CIF card [CIF]
