ReP3 is Hausmannite-like structured and crystallizes in the orthorhombic Pnma space group. Re(1) is bonded to one P(1), two equivalent P(2), and three equivalent P(3) atoms to form ReP6 octahedra that share corners with four equivalent Re(1)P6 octahedra, corners with two equivalent P(3)Re3P tetrahedra, corners with four equivalent P(2)Re2P2 tetrahedra, and edges with two equivalent Re(1)P6 octahedra. The corner-sharing octahedral tilt angles are 54°. There are three inequivalent P sites. In the first P site, P(2) is bonded to two equivalent Re(1), one P(1), and one P(3) atom to form distorted PRe2P2 tetrahedra that share corners with four equivalent Re(1)P6 octahedra, corners with two equivalent P(2)Re2P2 tetrahedra, corners with four equivalent P(3)Re3P tetrahedra, and  an edgeedge with one P(3)Re3P tetrahedra. The corner-sharing octahedral tilt angles range from 51-74°. In the second P site, P(1) is bonded in a distorted rectangular see-saw-like geometry to one Re(1), one P(2), and two equivalent P(1) atoms. In the third P site, P(3) is bonded to three equivalent Re(1) and one P(2) atom to form PRe3P tetrahedra that share corners with two equivalent Re(1)P6 octahedra, corners with four equivalent P(2)Re2P2 tetrahedra, corners with six equivalent P(3)Re3P tetrahedra, and  an edgeedge with one P(2)Re2P2 tetrahedra. The corner-sharing octahedral tilt angles are 64°.

The corner-sharing octahedral tilt angles are 54°. The Re(1)-P(1) bond length is 2.36 Å. Both Re(1)-P(2) bond lengths are 2.35 Å. There is one shorter (2.37 Å) and two longer (2.46 Å) Re(1)-P(3) bond lengths. There are three inequivalent P sites.

The corner-sharing octahedral tilt angles range from 51-74°. The P(2)-P(1) bond length is 2.20 Å. The P(2)-P(3) bond length is 2.23 Å. In the second P site, P(1) is bonded in a distorted rectangular see-saw-like geometry to one Re(1), one P(2), and two equivalent P(1) atoms. Both P(1)-P(1) bond lengths are 2.21 Å.
