The material described by EuP3 crystallizes in the monoclinic C2/m space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 7-coordinate geometry to one P(1), one P(2), two equivalent P(4), and four equivalent P(3) atoms. In the second Eu site, Eu(2) is bonded in a 9-coordinate geometry to one P(1), four equivalent P(3), and four equivalent P(4) atoms. There are four inequivalent P sites. In the first P site, P(1) is bonded in a 5-coordinate geometry to one Eu(1), one Eu(2), one P(2), and two equivalent P(3) atoms. In the second P site, P(2) is bonded in a distorted tetrahedral geometry to one Eu(1), one P(1), and two equivalent P(4) atoms. In the third P site, P(3) is bonded in a 6-coordinate geometry to two equivalent Eu(1), two equivalent Eu(2), one P(1), and one P(3) atom. In the fourth P site, P(4) is bonded in a 5-coordinate geometry to one Eu(1), two equivalent Eu(2), one P(2), and one P(4) atom. is represented by the CIF file [CIF]
