Materials Data on PaSe3 by Materials Project

PaSe3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pa5+ is bonded to twelve equivalent Se+1.67- atoms to form a mixture of face and corner-sharing PaSe12 cuboctahedra. There are six shorter (3.07 Å) and six longer (3.12 Å) Pa–Se bond lengths. Se+1.67- is bonded in a distorted see-saw-like geometry to four equivalent Pa5+ atoms.
