The compound described by Y2GaN3 crystallizes in the orthorhombic Cmc2_1 space group. Y(1) is bonded to one N(2) and four equivalent N(1) atoms to form distorted YN5 trigonal bipyramids that share corners with four equivalent Ga(1)N4 tetrahedra, corners with five equivalent Y(1)N5 trigonal bipyramids,  an edgeedge with one Ga(1)N4 tetrahedra, and edges with four equivalent Y(1)N5 trigonal bipyramids. Ga(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form GaN4 tetrahedra that share corners with two equivalent Ga(1)N4 tetrahedra, corners with eight equivalent Y(1)N5 trigonal bipyramids, and edges with two equivalent Y(1)N5 trigonal bipyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded to four equivalent Y(1) and one Ga(1) atom to form distorted NY4Ga trigonal bipyramids that share corners with four equivalent N(2)Y2Ga2 tetrahedra, corners with five equivalent N(1)Y4Ga trigonal bipyramids,  an edgeedge with one N(2)Y2Ga2 tetrahedra, and edges with four equivalent N(1)Y4Ga trigonal bipyramids. In the second N site, N(2) is bonded to two equivalent Y(1) and two equivalent Ga(1) atoms to form NY2Ga2 tetrahedra that share corners with two equivalent N(2)Y2Ga2 tetrahedra, corners with eight equivalent N(1)Y4Ga trigonal bipyramids, and edges with two equivalent N(1)Y4Ga trigonal bipyramids. is represented by the CIF card [CIF]
