The crystal structure described by PmNi3 crystallizes in the hexagonal P6_3/mmc space group. Pm(1) is bonded to twelve equivalent Ni(1) atoms to form a mixture of distorted corner and face-sharing PmNi12 cuboctahedra. Ni(1) is bonded in a 10-coordinate geometry to four equivalent Pm(1) and six equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
