Materials Data on Dy(Ni2As)2 by Materials Project

Kristin Persson
DyNi4As2 crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Dy is bonded to six equivalent As atoms to form a mixture of distorted edge and corner-sharing DyAs6 octahedra. The corner-sharing octahedral tilt angles are 40°. There are two shorter (2.89 Å) and four longer (2.92 Å) Dy–As bond lengths. Ni is bonded in a 3-coordinate geometry to three equivalent As atoms. There are two shorter (2.40 Å) and one longer (2.41 Å)...
