Materials Data on Y3Ni by Materials Project
Y3Ni is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two Y3Ni sheets oriented in the (0, 0, 1) direction. there are two inequivalent Y sites. In the first Y site, Y is bonded in a distorted water-like geometry to two equivalent Ni atoms. There are one shorter (2.78 Å) and one longer (2.84 Å) Y–Ni bond lengths. In the second Y site, Y is bonded in a distorted bent 150 degrees geometry to two equivalent Ni atoms. There are one shorter (2.75 Å) and one longer (2.80 Å) Y–Ni bond lengths. Ni is bonded in a 6-coordinate geometry to six Y atoms.
