CrFeAs crystallizes in the hexagonal P-62m space group. Cr(1) is bonded in a 5-coordinate geometry to one As(2) and four equivalent As(1) atoms. Fe(1) is bonded in a 4-coordinate geometry to 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 distorted q6 geometry to three equivalent Cr(1) and six equivalent Fe(1) atoms. In the second As site, As(1) is bonded in a 9-coordinate geometry to six equivalent Cr(1) and three equivalent Fe(1) atoms.
CrFeAs crystallizes in the hexagonal P-62m space group. Cr(1) is bonded in a 5-coordinate geometry to one As(2) and four equivalent As(1) atoms. The Cr(1)-As(2) bond length is 2.50 Å. All Cr(1)-As(1) bond lengths are 2.60 Å. Fe(1) is bonded in a 4-coordinate geometry to two equivalent As(1) and two equivalent As(2) atoms. Both Fe(1)-As(1) bond lengths are 2.33 Å. Both Fe(1)-As(2) bond lengths are 2.37 Å. There are two inequivalent As sites. In the first As site, As(2) is bonded in a distorted q6 geometry to three equivalent Cr(1) and six equivalent Fe(1) atoms. In the second As site, As(1) is bonded in a 9-coordinate geometry to six equivalent Cr(1) and three equivalent Fe(1) atoms.
