Eu3Rh is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. In the second Eu site, Eu(2) is bonded in a bent 150 degrees geometry to two equivalent Rh(1) atoms. Rh(1) is bonded in a 8-coordinate geometry to two equivalent Eu(2) and six equivalent Eu(1) atoms.
Eu3Rh is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. There are a spread of Eu(1)-Rh(1) bond distances ranging from 2.97-3.40 Å. In the second Eu site, Eu(2) is bonded in a bent 150 degrees geometry to two equivalent Rh(1) atoms. There is one shorter (2.87 Å) and one longer (2.95 Å) Eu(2)-Rh(1) bond length. Rh(1) is bonded in a 8-coordinate geometry to two equivalent Eu(2) and six equivalent Eu(1) atoms.
