The structure described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
