La La Mg Co
MgLa2Co crystallizes in the triclinic P1 space group. Mg(1) is bonded in a single-bond geometry to one La(1) and one Co(1) atom. The Mg(1)-La(1) bond length is 3.81 Å. The Mg(1)-Co(1) bond length is 0.90 Å. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 6-coordinate geometry to one Mg(1), two equivalent La(1), two equivalent La(2), and one Co(1) atom. Both La(1)-La(1) bond lengths are 3.73 Å. There is one shorter (2.74 Å) and one longer (3.59 Å) La(1)-La(2) bond length. The La(1)-Co(1) bond length is 2.79 Å. In the second La site, La(2) is bonded in a single-bond geometry to two equivalent La(1) and one Co(1) atom. The La(2)-Co(1) bond length is 0.18 Å. Co(1) is bonded in a distorted single-bond geometry to one Mg(1), one La(1), and one La(2) atom.
