Be Nb Rh
BeNbRh crystallizes in the trigonal R3m space group. Be(1) is bonded to one Nb(1) and three equivalent Rh(1) atoms to form distorted BeNbRh3 tetrahedra that share corners with three equivalent Rh(1)Be3Nb3 octahedra, corners with three equivalent Nb(1)BeRh3 tetrahedra, corners with six equivalent Be(1)NbRh3 tetrahedra, and edges with three equivalent Nb(1)BeRh3 tetrahedra. The corner-sharing octahedral tilt angles are 63°. The Be(1)-Nb(1) bond length is 0.93 Å. All Be(1)-Rh(1) bond lengths are 2.66 Å. Nb(1) is bonded to one Be(1) and three equivalent Rh(1) atoms to form distorted NbBeRh3 tetrahedra that share corners with three equivalent Rh(1)Be3Nb3 octahedra, corners with three equivalent Be(1)NbRh3 tetrahedra, corners with six equivalent Nb(1)BeRh3 tetrahedra, and edges with three equivalent Be(1)NbRh3 tetrahedra. The corner-sharing octahedral tilt angles are 63°. All Nb(1)-Rh(1) bond lengths are 2.66 Å. Rh(1) is bonded to three equivalent Be(1) and three equivalent Nb(1) atoms to form distorted RhBe3Nb3 octahedra that share corners with three equivalent Be(1)NbRh3 tetrahedra, corners with three equivalent Nb(1)BeRh3 tetrahedra, and edges with six equivalent Rh(1)Be3Nb3 octahedra.
