PrAgAl3 crystallizes in the tetragonal I4mm space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Ag(1), four equivalent Al(2), and eight equivalent Al(1) atoms. Ag(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1), one Al(2), and four equivalent Al(1) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 2-coordinate geometry to four equivalent Pr(1), two equivalent Ag(1), and two equivalent Al(2) atoms. In the second Al site, Al(2) is bonded in a distorted single-bond geometry to four equivalent Pr(1), one Ag(1), and four equivalent Al(1) atoms.
PrAgAl3 crystallizes in the tetragonal I4mm space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Ag(1), four equivalent Al(2), and eight equivalent Al(1) atoms. All Pr(1)-Ag(1) bond lengths are 3.38 Å. All Pr(1)-Al(2) bond lengths are 3.22 Å. There are four shorter (3.41 Å) and four longer (3.61 Å) Pr(1)-Al(1) bond lengths. Ag(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1), one Al(2), and four equivalent Al(1) atoms. The Ag(1)-Al(2) bond length is 2.52 Å. All Ag(1)-Al(1) bond lengths are 2.58 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 2-coordinate geometry to four equivalent Pr(1), two equivalent Ag(1), and two equivalent Al(2) atoms. Both Al(1)-Al(2) bond lengths are 2.69 Å. In the second Al site, Al(2) is bonded in a distorted single-bond geometry to four equivalent Pr(1), one Ag(1), and four equivalent Al(1) atoms.
