CrFeAs2 is Modderite-derived structured and crystallizes in the orthorhombic Pmn2_1 space group. Cr(1) is bonded in a 6-coordinate geometry to three equivalent As(1) and three equivalent As(2) atoms. Fe(1) is bonded in a 6-coordinate geometry to three equivalent As(1) and three equivalent As(2) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 6-coordinate geometry to three equivalent Cr(1) and three equivalent Fe(1) atoms. In the second As site, As(2) is bonded in a 6-coordinate geometry to three equivalent Cr(1) and three equivalent Fe(1) atoms.
CrFeAs2 is Modderite-derived structured and crystallizes in the orthorhombic Pmn2_1 space group. Cr(1) is bonded in a 6-coordinate geometry to three equivalent As(1) and three equivalent As(2) atoms. There is one shorter (2.38 Å) and two longer (2.47 Å) Cr(1)-As(1) bond lengths. There are two shorter (2.50 Å) and one longer (2.53 Å) Cr(1)-As(2) bond length.
