La La Nb Zn
La2NbZn crystallizes in the monoclinic Cm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 9-coordinate geometry to one La(2), four equivalent La(1), three equivalent Nb(1), and one Zn(1) atom. The La(1)-La(2) bond length is 3.11 Å. All La(1)-La(1) bond lengths are 3.33 Å. There is one shorter (3.49 Å) and two longer (3.98 Å) La(1)-Nb(1) bond lengths. The La(1)-Zn(1) bond length is 3.45 Å. In the second La site, La(2) is bonded in a 1-coordinate geometry to one La(1), one Nb(1), and one Zn(1) atom. The La(2)-Nb(1) bond length is 3.49 Å. The La(2)-Zn(1) bond length is 1.58 Å. Nb(1) is bonded in a 9-coordinate geometry to one La(2), three equivalent La(1), four equivalent Nb(1), and one Zn(1) atom. All Nb(1)-Nb(1) bond lengths are 3.33 Å. The Nb(1)-Zn(1) bond length is 3.14 Å. Zn(1) is bonded in a 1-coordinate geometry to one La(1), one La(2), and one Nb(1) atom.
