Ba Tl Pd Rh
BaRhPdTl crystallizes in the trigonal R3m space group. Ba(1) is bonded to three equivalent Rh(1), one Pd(1), and one Tl(1) atom to form distorted BaTlPdRh3 trigonal bipyramids that share corners with six equivalent Ba(1)TlPdRh3 trigonal bipyramids and  a cornercorner with one Rh(1)Ba3Pd trigonal pyramid. All Ba(1)-Rh(1) bond lengths are 2.99 Å. The Ba(1)-Pd(1) bond length is 2.19 Å. The Ba(1)-Tl(1) bond length is 2.19 Å. Rh(1) is bonded to three equivalent Ba(1) and one Pd(1) atom to form distorted RhBa3Pd trigonal pyramids that share  a cornercorner with one Ba(1)TlPdRh3 trigonal bipyramid and corners with six equivalent Rh(1)Ba3Pd trigonal pyramids. The Rh(1)-Pd(1) bond length is 2.19 Å. Pd(1) is bonded in a distorted single-bond geometry to one Ba(1) and one Rh(1) atom. Tl(1) is bonded in a distorted single-bond geometry to one Ba(1) atom.
