Cr3Fe3SiAs2 crystallizes in the hexagonal P-62m space group. Cr(1) is bonded in a 11-coordinate geometry to six equivalent Fe(1), one Si(1), and four equivalent As(1) atoms. Fe(1) is bonded in a 12-coordinate geometry to six equivalent Cr(1), two equivalent Fe(1), two equivalent Si(1), and two equivalent As(1) atoms. Si(1) is bonded in a distorted q6 geometry to three equivalent Cr(1) and six equivalent Fe(1) atoms. As(1) is bonded in a 9-coordinate geometry to six equivalent Cr(1) and three equivalent Fe(1) atoms.
Cr3Fe3SiAs2 crystallizes in the hexagonal P-62m space group. Cr(1) is bonded in a 11-coordinate geometry to six equivalent Fe(1), one Si(1), and four equivalent As(1) atoms.
