Pr Lu Lu W
Lu2PrW crystallizes in the trigonal R3m space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a single-bond geometry to one W(1) atom. The Lu(1)-W(1) bond length is 2.10 Å. In the second Lu site, Lu(2) is bonded in a distorted linear geometry to one Pr(1) and one W(1) atom. The Lu(2)-Pr(1) bond length is 2.10 Å. The Lu(2)-W(1) bond length is 2.10 Å. Pr(1) is bonded to one Lu(2) and three equivalent W(1) atoms to form PrLuW3 trigonal pyramids that share  a cornercorner with one W(1)Pr3Lu2 trigonal bipyramid and corners with six equivalent Pr(1)LuW3 trigonal pyramids. All Pr(1)-W(1) bond lengths are 3.00 Å. W(1) is bonded to one Lu(1), one Lu(2), and three equivalent Pr(1) atoms to form distorted WPr3Lu2 trigonal bipyramids that share corners with six equivalent W(1)Pr3Lu2 trigonal bipyramids and  a cornercorner with one Pr(1)LuW3 trigonal pyramid.
