Materials Data on HfCuAu2 by Materials Project
HfAu2Cu crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two HfAu2Cu ribbons oriented in the (1, 0, 0) direction. Hf is bonded in a linear geometry to two equivalent Au atoms. Both Hf–Au bond lengths are 2.58 Å. Au is bonded in a linear geometry to one Hf and one Cu atom. The Au–Cu bond length is 2.47 Å. Cu is bonded in a linear geometry to two equivalent Au atoms.
