Materials Data on Er3(AlNi3)2 by Materials Project

Er3(Ni3Al)2 crystallizes in the cubic Im-3m space group. The structure is three-dimensional. Er is bonded in a 12-coordinate geometry to eight equivalent Ni and four equivalent Al atoms. There are four shorter (2.76 Å) and four longer (2.99 Å) Er–Ni bond lengths. All Er–Al bond lengths are 3.15 Å. Ni is bonded in a 12-coordinate geometry to four equivalent Er, four equivalent Ni, and two equivalent Al atoms. All Ni–Ni bond lengths are 2.56 Å. Both Ni–Al bond lengths are 2.46 Å. Al is bonded in a distorted hexagonal planar geometry to six equivalent Er and six equivalent Ni atoms.
