Materials Data on YAlCu2 by Materials Project
YCu2Al crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two YCu2Al ribbons oriented in the (1, 0, 0) direction. Y is bonded in a linear geometry to two equivalent Cu atoms. Both Y–Cu bond lengths are 2.80 Å. Cu is bonded in a linear geometry to one Y and one Al atom. The Cu–Al bond length is 2.44 Å. Al is bonded in a linear geometry to two equivalent Cu atoms.
