La La Mg W
MgLa2W crystallizes in the triclinic P1 space group. Mg(1) is bonded in a 5-coordinate geometry to one La(2), two equivalent La(1), and two equivalent W(1) atoms. The Mg(1)-La(2) bond length is 2.50 Å. There is one shorter (2.11 Å) and one longer (2.66 Å) Mg(1)-La(1) bond length. There is one shorter (2.60 Å) and one longer (3.14 Å) Mg(1)-W(1) bond length. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 5-coordinate geometry to two equivalent Mg(1), one La(2), and two equivalent W(1) atoms. The La(1)-La(2) bond length is 2.79 Å. There is one shorter (2.50 Å) and one longer (2.98 Å) La(1)-W(1) bond length. In the second La site, La(2) is bonded in a 1-coordinate geometry to one Mg(1), one La(1), and two equivalent W(1) atoms. There is one shorter (2.11 Å) and one longer (2.66 Å) La(2)-W(1) bond length. W(1) is bonded in a 6-coordinate geometry to two equivalent Mg(1), two equivalent La(1), and two equivalent La(2) atoms.
