YRhBr crystallizes in the trigonal R3m space group. Y(1) is bonded to three equivalent Rh(1) and four equivalent Br(1) atoms to form distorted YRh3Br4 hexagonal pyramids that share corners with three equivalent Br(1)Y4Rh3 hexagonal pyramids, corners with six equivalent Y(1)Rh3Br4 hexagonal pyramids, edges with three equivalent Br(1)Y4Rh3 hexagonal pyramids, and edges with six equivalent Y(1)Rh3Br4 hexagonal pyramids. All Y(1)-Rh(1) bond lengths are 2.70 Å. There are three shorter (2.72 Å) and one longer (3.40 Å) Y(1)-Br(1) bond length. Rh(1) is bonded in a hexagonal planar geometry to three equivalent Y(1) and three equivalent Br(1) atoms. All Rh(1)-Br(1) bond lengths are 2.70 Å. Br(1) is bonded to four equivalent Y(1) and three equivalent Rh(1) atoms to form BrY4Rh3 hexagonal pyramids that share corners with three equivalent Y(1)Rh3Br4 hexagonal pyramids, corners with six equivalent Br(1)Y4Rh3 hexagonal pyramids, edges with three equivalent Y(1)Rh3Br4 hexagonal pyramids, and edges with six equivalent Br(1)Y4Rh3 hexagonal pyramids.
