CoMnSn crystallizes in the hexagonal P6_3/mmc space group. Mn(1) is bonded in a 14-coordinate geometry to two equivalent Mn(1), six equivalent Co(1), and six equivalent Sn(1) atoms. Co(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1) and five equivalent Sn(1) atoms. Sn(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1) and five equivalent Co(1) atoms.
CoMnSn crystallizes in the hexagonal P6_3/mmc space group. Mn(1) is bonded in a 14-coordinate geometry to two equivalent Mn(1), six equivalent Co(1), and six equivalent Sn(1) atoms. Both Mn(1)-Mn(1) bond lengths are 2.70 Å. All Mn(1)-Co(1) bond lengths are 2.86 Å. All Mn(1)-Sn(1) bond lengths are 2.86 Å. Co(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1) and five equivalent Sn(1) atoms. There are three shorter (2.52 Å) and two longer (2.70 Å) Co(1)-Sn(1) bond lengths. Sn(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1) and five equivalent Co(1) atoms.
