The structure described by PaP2 crystallizes in the tetragonal P4/nmm space group. Pa(1) is bonded in a 9-coordinate geometry to four equivalent P(2) and five equivalent P(1) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to five equivalent Pa(1) atoms to form a mixture of distorted corner and edge-sharing PPa5 trigonal bipyramids. In the second P site, P(2) is bonded in a 8-coordinate geometry to four equivalent Pa(1) and four equivalent P(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
