The crystal structure described by PaPt3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Pa(1) is bonded to twelve Pt(1,1) atoms to form a mixture of corner and face-sharing PaPt12 cuboctahedra. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 12-coordinate geometry to four equivalent Pa(1) and eight equivalent Pt(1) atoms. In the second Pt site, Pt(1) is bonded in a 12-coordinate geometry to four equivalent Pa(1) and eight Pt(1,1) atoms. is represented by the CIF card [CIF]
