CoMnSn crystallizes in the hexagonal P6_3/mmc space group. Mn(1) is bonded in a 11-coordinate geometry to six equivalent Co(1) and five equivalent Sn(1) atoms. Co(1) is bonded in a 14-coordinate geometry to six equivalent Mn(1), two equivalent Co(1), and six equivalent Sn(1) atoms. Sn(1) is bonded to five equivalent Mn(1) and six equivalent Co(1) atoms to form a mixture of distorted face and corner-sharing SnMn5Co6 trigonal bipyramids.
CoMnSn crystallizes in the hexagonal P6_3/mmc space group. Mn(1) is bonded in a 11-coordinate geometry to six equivalent Co(1) and five equivalent Sn(1) atoms. All Mn(1)-Co(1) bond lengths are 2.83 Å. There are three shorter (2.52 Å) and two longer (2.58 Å) Mn(1)-Sn(1) bond lengths. Co(1) is bonded in a 14-coordinate geometry to six equivalent Mn(1), two equivalent Co(1), and six equivalent Sn(1) atoms. Both Co(1)-Co(1) bond lengths are 2.58 Å. All Co(1)-Sn(1) bond lengths are 2.83 Å. Sn(1) is bonded to five equivalent Mn(1) and six equivalent Co(1) atoms to form a mixture of distorted face and corner-sharing SnMn5Co6 trigonal bipyramids.
