Mg2EuFe crystallizes in the trigonal P-3m1 space group. Mg(1) is bonded in a distorted trigonal planar geometry to three equivalent Fe(1) atoms. Eu(1) is bonded in a linear geometry to two equivalent Fe(1) atoms. Fe(1) is bonded to six equivalent Mg(1) and two equivalent Eu(1) atoms to form a mixture of corner and edge-sharing FeEu2Mg6 hexagonal bipyramids.
Mg2EuFe crystallizes in the trigonal P-3m1 space group. Mg(1) is bonded in a distorted trigonal planar geometry to three equivalent Fe(1) atoms. All Mg(1)-Fe(1) bond lengths are 2.80 Å. Eu(1) is bonded in a linear geometry to two equivalent Fe(1) atoms. Both Eu(1)-Fe(1) bond lengths are 2.57 Å. Fe(1) is bonded to six equivalent Mg(1) and two equivalent Eu(1) atoms to form a mixture of corner and edge-sharing FeEu2Mg6 hexagonal bipyramids.
