CrNiAs crystallizes in the hexagonal P-62m space group. Cr(1) is bonded in a 11-coordinate geometry to six equivalent Ni(1), one As(2), and four equivalent As(1) atoms. Ni(1) is bonded in a 4-coordinate geometry to six equivalent Cr(1), two equivalent As(1), and two equivalent As(2) atoms. There are two inequivalent As sites. In the first As site, As(2) is bonded in a 9-coordinate geometry to three equivalent Cr(1) and six equivalent Ni(1) atoms. In the second As site, As(1) is bonded in a 9-coordinate geometry to six equivalent Cr(1) and three equivalent Ni(1) atoms.
CrNiAs crystallizes in the hexagonal P-62m space group. Cr(1) is bonded in a 11-coordinate geometry to six equivalent Ni(1), one As(2), and four equivalent As(1) atoms. There are two shorter (2.78 Å) and four longer (2.86 Å) Cr(1)-Ni(1) bond lengths. The Cr(1)-As(2) bond length is 2.52 Å. All Cr(1)-As(1) bond lengths are 2.62 Å. Ni(1) is bonded in a 4-coordinate geometry to six equivalent Cr(1), two equivalent As(1), and two equivalent As(2) atoms. Both Ni(1)-As(1) bond lengths are 2.35 Å. Both Ni(1)-As(2) bond lengths are 2.41 Å. There are two inequivalent As sites. In the first As site, As(2) is bonded in a 9-coordinate geometry to three equivalent Cr(1) and six equivalent Ni(1) atoms. In the second As site, As(1) is bonded in a 9-coordinate geometry to six equivalent Cr(1) and three equivalent Ni(1) atoms.
