The material described by Eu(Ni5P3)2 crystallizes in the orthorhombic Cmce space group. Eu(1) is bonded in a 18-coordinate geometry to four equivalent Ni(4), six equivalent Ni(3), two equivalent P(2), two equivalent P(3), and four equivalent P(1) atoms. There are four inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 4-coordinate geometry to two equivalent P(1) and two equivalent P(3) atoms. In the second Ni site, Ni(2) is bonded in a 4-coordinate geometry to two equivalent P(2) and two equivalent P(3) atoms. In the third Ni site, Ni(3) is bonded to three equivalent Eu(1), two equivalent P(1), and two equivalent P(2) atoms to form distorted NiEu3P4 tetrahedra that share corners with six equivalent Ni(4)EuP4 tetrahedra, corners with nine equivalent Ni(3)Eu3P4 tetrahedra, edges with four equivalent Ni(4)EuP4 tetrahedra, faces with two equivalent Ni(4)EuP4 tetrahedra, and faces with three equivalent Ni(3)Eu3P4 tetrahedra. In the fourth Ni site, Ni(4) is bonded to one Eu(1), one P(1), one P(2), and two equivalent P(3) atoms to form distorted NiEuP4 tetrahedra that share corners with three equivalent Ni(3)Eu3P4 tetrahedra, corners with five equivalent Ni(4)EuP4 tetrahedra, edges with two equivalent Ni(3)Eu3P4 tetrahedra, edges with three equivalent Ni(4)EuP4 tetrahedra, and  a faceface with one Ni(3)Eu3P4 tetrahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded in a 8-coordinate geometry to two equivalent Eu(1), two equivalent Ni(1), two equivalent Ni(3), and two equivalent Ni(4) atoms. In the second P site, P(2) is bonded in a 6-coordinate geometry to one Eu(1), two equivalent Ni(2), two equivalent Ni(3), and two equivalent Ni(4) atoms. In the third P site, P(3) is bonded in a 8-coordinate geometry to one Eu(1), two equivalent Ni(1), two equivalent Ni(2), and four equivalent Ni(4) atoms. is represented by the CIF card [CIF]
