La3PBr3 crystallizes in the cubic I4_132 space group. La(1) is bonded to two equivalent P(1) and four equivalent Br(1) atoms to form a mixture of corner and edge-sharing LaP2Br4 octahedra. The corner-sharing octahedral tilt angles range from 4-8°. P(1) is bonded to six equivalent La(1) atoms to form edge-sharing PLa6 octahedra. Br(1) is bonded in a rectangular see-saw-like geometry to four equivalent La(1) atoms.

The corner-sharing octahedral tilt angles range from 4-8°. Both La(1)-P(1) bond lengths are 2.87 Å. There are two shorter (3.12 Å) and two longer (3.17 Å) La(1)-Br(1) bond lengths. P(1) is bonded to six equivalent La(1) atoms to form edge-sharing PLa6 octahedra. Br(1) is bonded in a rectangular see-saw-like geometry to four equivalent La(1) atoms.
