La Mg Fe Co
MgLaFeCo crystallizes in the trigonal R3m space group. Mg(1) is bonded in a single-bond geometry to one La(1), three equivalent Fe(1), and three equivalent Co(1) atoms. The Mg(1)-La(1) bond length is 0.64 Å. All Mg(1)-Fe(1) bond lengths are 2.78 Å. All Mg(1)-Co(1) bond lengths are 2.76 Å. La(1) is bonded in a single-bond geometry to one Mg(1), four equivalent Fe(1), and three equivalent Co(1) atoms. There are three shorter (2.76 Å) and one longer (3.68 Å) La(1)-Fe(1) bond length. All La(1)-Co(1) bond lengths are 2.78 Å. Fe(1) is bonded in a distorted q6 geometry to three equivalent Mg(1), four equivalent La(1), and three equivalent Co(1) atoms. All Fe(1)-Co(1) bond lengths are 2.76 Å. Co(1) is bonded in a distorted q6 geometry to three equivalent Mg(1), three equivalent La(1), and three equivalent Fe(1) atoms.
