Materials Data on AlCuNi2 by Materials Project
Ni2CuAl crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two Ni2CuAl ribbons oriented in the (1, 0, 0) direction. Ni is bonded in a linear geometry to one Cu and one Al atom. The Ni–Cu bond length is 2.29 Å. The Ni–Al bond length is 2.17 Å. Cu is bonded in a linear geometry to two equivalent Ni atoms. Al is bonded in a linear geometry to two equivalent Ni atoms.
