PrAuGa3 crystallizes in the tetragonal I4mm space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Au(1), four equivalent Ga(2), and eight equivalent Ga(1) atoms. Au(1) is bonded in a 5-coordinate geometry to four equivalent Pr(1), one Ga(2), and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted bent 120 degrees geometry to four equivalent Pr(1) and two equivalent Au(1) atoms. In the second Ga site, Ga(2) is bonded in a distorted single-bond geometry to four equivalent Pr(1) and one Au(1) atom.
PrAuGa3 crystallizes in the tetragonal I4mm space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Au(1), four equivalent Ga(2), and eight equivalent Ga(1) atoms. All Pr(1)-Au(1) bond lengths are 3.39 Å. All Pr(1)-Ga(2) bond lengths are 3.23 Å. There are four shorter (3.34 Å) and four longer (3.57 Å) Pr(1)-Ga(1) bond lengths. Au(1) is bonded in a 5-coordinate geometry to four equivalent Pr(1), one Ga(2), and four equivalent Ga(1) atoms. The Au(1)-Ga(2) bond length is 2.50 Å. All Au(1)-Ga(1) bond lengths are 2.56 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted bent 120 degrees geometry to four equivalent Pr(1) and two equivalent Au(1) atoms. In the second Ga site, Ga(2) is bonded in a distorted single-bond geometry to four equivalent Pr(1) and one Au(1) atom.
