Materials Data on LaZn3Ni2 by Materials Project

LaNi2Zn3 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. La is bonded in a distorted hexagonal planar geometry to six equivalent Ni and twelve equivalent Zn atoms. All La–Ni bond lengths are 3.04 Å. All La–Zn bond lengths are 3.34 Å. Ni is bonded in a 9-coordinate geometry to three equivalent La and six equivalent Zn atoms. All Ni–Zn bond lengths are 2.56 Å. Zn is bonded to four equivalent La, four equivalent Ni, and four equivalent Zn atoms to form a mixture of distorted face, edge, and corner-sharing ZnLa4Zn4Ni4 cuboctahedra. All Zn–Zn bond lengths are 2.63 Å.
