La Zn Co Co
LaCo2Zn crystallizes in the monoclinic Pm space group. La(1) is bonded in a 2-coordinate geometry to one Co(1), one Co(2), and one Zn(1) atom. The La(1)-Co(1) bond length is 0.95 Å. The La(1)-Co(2) bond length is 0.94 Å. The La(1)-Zn(1) bond length is 3.42 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted L-shaped geometry to one La(1), one Co(2), and one Zn(1) atom. The Co(1)-Co(2) bond length is 0.40 Å. The Co(1)-Zn(1) bond length is 2.80 Å. In the second Co site, Co(2) is bonded in a distorted L-shaped geometry to one La(1), one Co(1), and one Zn(1) atom. The Co(2)-Zn(1) bond length is 2.86 Å. Zn(1) is bonded to one La(1), one Co(1), one Co(2), and four equivalent Zn(1) atoms to form a mixture of distorted edge and corner-sharing ZnLaZn4Co2 pentagonal bipyramids. All Zn(1)-Zn(1) bond lengths are 3.04 Å.
