The material structure described by SrNi5As3 crystallizes in the orthorhombic Cmcm space group. Sr(1) is bonded in a 15-coordinate geometry to four equivalent Ni(1), four equivalent Ni(3), three equivalent As(2), and four equivalent As(1) 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), one As(2), and three equivalent As(1) atoms. In the second Ni site, Ni(2) is bonded in a 4-coordinate geometry to four equivalent As(1) atoms. In the third Ni site, Ni(3) is bonded in a 4-coordinate geometry to two equivalent Sr(1), two equivalent As(1), and two equivalent As(2) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 9-coordinate geometry to two equivalent Sr(1), two equivalent Ni(2), two equivalent Ni(3), and three equivalent Ni(1) atoms. In the second As site, As(2) is bonded in a 9-coordinate geometry to three equivalent Sr(1), two equivalent Ni(1), and four equivalent Ni(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
