The crystal structure described by Li3YN2 crystallizes in the cubic Ia-3 space group. Li(1) is bonded in a distorted trigonal planar geometry to one N(1) and two equivalent N(2) atoms. Y(1) is bonded to one N(1) and three equivalent N(2) atoms to form corner-sharing YN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a hexagonal bipyramidal geometry to six equivalent Li(1) and two equivalent Y(1) atoms. In the second N site, N(2) is bonded in a 6-coordinate geometry to four equivalent Li(1) and two equivalent Y(1) atoms. is represented by the CIF file [CIF]
