Materials Data on HfMgNi2 by Materials Project
MgHfNi2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two MgHfNi2 ribbons oriented in the (1, 0, 0) direction. Mg is bonded in a linear geometry to two equivalent Ni atoms. Both Mg–Ni bond lengths are 2.63 Å. Hf is bonded in a linear geometry to two equivalent Ni atoms. Both Hf–Ni bond lengths are 2.19 Å. Ni is bonded in a linear geometry to one Mg and one Hf atom.
