SrNi5P3 crystallizes in the orthorhombic Cmcm space group. Sr(1) is bonded in a 15-coordinate geometry to four equivalent Ni(1), four equivalent Ni(2), three equivalent P(1), and four equivalent P(2) atoms. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1), two equivalent P(1), and two equivalent P(2) atoms. In the second Ni site, Ni(2) is bonded in a 4-coordinate geometry to two equivalent Sr(1), one P(1), and three equivalent P(2) atoms. In the third Ni site, Ni(3) is bonded in a 4-coordinate geometry to four equivalent P(2) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 9-coordinate geometry to three equivalent Sr(1), two equivalent Ni(2), and four equivalent Ni(1) atoms. In the second P site, P(2) is bonded in a 9-coordinate geometry to two equivalent Sr(1), two equivalent Ni(1), two equivalent Ni(3), and three equivalent Ni(2) atoms.
SrNi5P3 crystallizes in the orthorhombic Cmcm space group. Sr(1) is bonded in a 15-coordinate geometry to four equivalent Ni(1), four equivalent Ni(2), three equivalent P(1), and four equivalent P(2) atoms. All Sr(1)-Ni(1) bond lengths are 3.29 Å.
