FeNiSn crystallizes in the hexagonal P-6m2 space group. Fe(1) is bonded in a 11-coordinate geometry to two equivalent Fe(1), three equivalent Ni(1), and six equivalent Sn(1) atoms. Ni(1) is bonded in a distorted trigonal planar geometry to three equivalent Fe(1), two equivalent Ni(1), and six equivalent Sn(1) atoms. Sn(1) is bonded in a 14-coordinate geometry to six equivalent Fe(1), six equivalent Ni(1), and two equivalent Sn(1) atoms.
