Y Rh Pb
YRhPb crystallizes in the trigonal R3m space group. Y(1) is bonded to four equivalent Rh(1) and four equivalent Pb(1) atoms to form distorted YRh4Pb4 hexagonal bipyramids that share corners with six equivalent Rh(1)Y4Pb3 hexagonal pyramids, corners with six equivalent Pb(1)Y4Rh3 hexagonal pyramids, edges with twelve equivalent Y(1)Rh4Pb4 hexagonal bipyramids, edges with three equivalent Rh(1)Y4Pb3 hexagonal pyramids, and edges with three equivalent Pb(1)Y4Rh3 hexagonal pyramids. There are three shorter (2.73 Å) and one longer (3.80 Å) Y(1)-Rh(1) bond length. There are three shorter (2.73 Å) and one longer (3.98 Å) Y(1)-Pb(1) bond length. Rh(1) is bonded to four equivalent Y(1) and three equivalent Pb(1) atoms to form distorted RhY4Pb3 hexagonal pyramids that share corners with six equivalent Y(1)Rh4Pb4 hexagonal bipyramids, corners with four equivalent Pb(1)Y4Rh3 hexagonal pyramids, corners with six equivalent Rh(1)Y4Pb3 hexagonal pyramids, edges with three equivalent Y(1)Rh4Pb4 hexagonal bipyramids, edges with six equivalent Rh(1)Y4Pb3 hexagonal pyramids, and edges with six equivalent Pb(1)Y4Rh3 hexagonal pyramids. All Rh(1)-Pb(1) bond lengths are 2.73 Å. Pb(1) is bonded to four equivalent Y(1) and three equivalent Rh(1) atoms to form distorted PbY4Rh3 hexagonal pyramids that share corners with six equivalent Y(1)Rh4Pb4 hexagonal bipyramids, corners with four equivalent Rh(1)Y4Pb3 hexagonal pyramids, corners with six equivalent Pb(1)Y4Rh3 hexagonal pyramids, edges with three equivalent Y(1)Rh4Pb4 hexagonal bipyramids, edges with six equivalent Rh(1)Y4Pb3 hexagonal pyramids, and edges with six equivalent Pb(1)Y4Rh3 hexagonal pyramids.
