Materials Data on Y(Ni2As)2 by Materials Project

YNi4As2 crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Y is bonded to six equivalent As atoms to form a mixture of distorted edge and corner-sharing YAs6 octahedra. The corner-sharing octahedral tilt angles are 40°. There are two shorter (2.90 Å) and four longer (2.92 Å) Y–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) Ni–As bond lengths. As is bonded in a 9-coordinate geometry to three equivalent Y and six equivalent Ni atoms.
