Pr Tl Tl Mo
PrMoTl2 crystallizes in the trigonal R3m space group. Pr(1) is bonded in a 5-coordinate geometry to three equivalent Mo(1), one Tl(1), and one Tl(2) atom. All Pr(1)-Mo(1) bond lengths are 3.04 Å. The Pr(1)-Tl(1) bond length is 2.46 Å. The Pr(1)-Tl(2) bond length is 2.46 Å. Mo(1) is bonded in a 10-coordinate geometry to three equivalent Pr(1), three equivalent Tl(2), and four equivalent Tl(1) atoms. All Mo(1)-Tl(2) bond lengths are 3.09 Å. There is one shorter (2.46 Å) and three longer (3.40 Å) Mo(1)-Tl(1) bond lengths. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a linear geometry to one Pr(1) and four equivalent Mo(1) atoms. In the second Tl site, Tl(2) is bonded in a 1-coordinate geometry to one Pr(1) and three equivalent Mo(1) atoms.
