Materials Data on LaCo2Ni3 by Materials Project
LaNi3.0Co2.0 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. La is bonded in a 6-coordinate geometry to six equivalent Co and twelve equivalent Ni atoms. All La–Co bond lengths are 2.86 Å. All La–Ni bond lengths are 3.18 Å. Co is bonded in a 12-coordinate geometry to three equivalent La and six equivalent Ni atoms. All Co–Ni bond lengths are 2.46 Å. Ni is bonded to four equivalent La, four equivalent Co, and four equivalent Ni atoms to form a mixture of edge, face, and corner-sharing NiLa4Co4Ni4 cuboctahedra. All Ni–Ni bond lengths are 2.48 Å.
