FeNiSn crystallizes in the hexagonal P6_3/mmc space group. Fe(1) is bonded in a 11-coordinate geometry to six equivalent Ni(1) and five equivalent Sn(1) atoms. Ni(1) is bonded in a 14-coordinate geometry to six equivalent Fe(1), two equivalent Ni(1), and six equivalent Sn(1) atoms. Sn(1) is bonded in a 11-coordinate geometry to five equivalent Fe(1) and six equivalent Ni(1) atoms.
FeNiSn crystallizes in the hexagonal P6_3/mmc space group. Fe(1) is bonded in a 11-coordinate geometry to six equivalent Ni(1) and five equivalent Sn(1) atoms. All Fe(1)-Ni(1) bond lengths are 2.84 Å. There are three shorter (2.52 Å) and two longer (2.63 Å) Fe(1)-Sn(1) bond lengths. Ni(1) is bonded in a 14-coordinate geometry to six equivalent Fe(1), two equivalent Ni(1), and six equivalent Sn(1) atoms. Both Ni(1)-Ni(1) bond lengths are 2.63 Å. All Ni(1)-Sn(1) bond lengths are 2.84 Å. Sn(1) is bonded in a 11-coordinate geometry to five equivalent Fe(1) and six equivalent Ni(1) atoms.
