The crystal structure described by Rh3P2 crystallizes in the tetragonal P-4m2 space group. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 4-coordinate geometry to four equivalent P(1) atoms. In the second Rh site, Rh(2) is bonded in a 5-coordinate geometry to five equivalent P(1) atoms. P(1) is bonded to two equivalent Rh(1) and five equivalent Rh(2) atoms to form a mixture of distorted face, corner, and edge-sharing PRh7 pentagonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
