Pr Ga Ga Te
PrGa2Te crystallizes in the trigonal R3m space group. Pr(1) is bonded in a distorted linear geometry to one Ga(1), one Ga(2), and three equivalent Te(1) atoms. The Pr(1)-Ga(1) bond length is 1.94 Å. The Pr(1)-Ga(2) bond length is 1.94 Å. All Pr(1)-Te(1) bond lengths are 3.04 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a linear geometry to one Pr(1) and one Te(1) atom. The Ga(1)-Te(1) bond length is 1.94 Å. In the second Ga site, Ga(2) is bonded in a single-bond geometry to one Pr(1) atom. Te(1) is bonded to three equivalent Pr(1) and one Ga(1) atom to form distorted corner-sharing TePr3Ga trigonal pyramids.
