YWN3 crystallizes in the orthorhombic Ama2 space group. Y(1) is bonded to one N(2), two equivalent N(3), and three equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing YN6 octahedra. The corner-sharing octahedral tilt angles are 62°. W(1) is bonded in a 5-coordinate geometry to one N(1), one N(3), and three equivalent N(2) atoms. There are three inequivalent N sites. In the first N site, N(1) is bonded to three equivalent Y(1) and one W(1) atom to form NY3W tetrahedra that share corners with six equivalent N(1)Y3W tetrahedra, corners with two equivalent N(2)YW3 trigonal pyramids, and edges with two equivalent N(2)YW3 trigonal pyramids. In the second N site, N(2) is bonded to one Y(1) and three equivalent W(1) atoms to form distorted NYW3 trigonal pyramids that share corners with two equivalent N(1)Y3W tetrahedra, corners with two equivalent N(2)YW3 trigonal pyramids, edges with two equivalent N(1)Y3W tetrahedra, and edges with two equivalent N(2)YW3 trigonal pyramids. In the third N site, N(3) is bonded in a trigonal planar geometry to two equivalent Y(1) and one W(1) atom.

The corner-sharing octahedral tilt angles are 62°. The Y(1)-N(2) bond length is 2.61 Å. Both Y(1)-N(3) bond lengths are 2.38 Å. There is one shorter (2.31 Å) and two longer (2.43 Å) Y(1)-N(1) bond lengths. W(1) is bonded in a 5-coordinate geometry to one N(1), one N(3), and three equivalent N(2) atoms. The W(1)-N(1) bond length is 1.87 Å. The W(1)-N(3) bond length is 1.82 Å. There are two shorter (2.01 Å) and one longer (2.17 Å) W(1)-N(2) bond length. There are three inequivalent N sites. In the first N site, N(1) is bonded to three equivalent Y(1) and one W(1) atom to form NY3W tetrahedra that share corners with six equivalent N(1)Y3W tetrahedra, corners with two equivalent N(2)YW3 trigonal pyramids, and edges with two equivalent N(2)YW3 trigonal pyramids.
