Y2Cd3N4 crystallizes in the monoclinic C2/c space group. Y(1) is bonded to two equivalent N(1) and four equivalent N(2) atoms to form a mixture of edge and corner-sharing YN6 octahedra. The corner-sharing octahedral tilt angles are 9°. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 4-coordinate geometry to one N(2) and three equivalent N(1) atoms. In the second Cd site, Cd(2) is bonded in a linear geometry to two equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Y(1), one Cd(2), and three equivalent Cd(1) atoms to form distorted NY2Cd4 octahedra that share corners with three equivalent N(1)Y2Cd4 octahedra, corners with five equivalent N(2)Y4Cd square pyramids, edges with three equivalent N(1)Y2Cd4 octahedra, and edges with three equivalent N(2)Y4Cd square pyramids. The corner-sharing octahedral tilt angles range from 15-18°. In the second N site, N(2) is bonded to four equivalent Y(1) and one Cd(1) atom to form distorted NY4Cd square pyramids that share corners with five equivalent N(1)Y2Cd4 octahedra, corners with two equivalent N(2)Y4Cd square pyramids, edges with three equivalent N(1)Y2Cd4 octahedra, and edges with five equivalent N(2)Y4Cd square pyramids. The corner-sharing octahedral tilt angles range from 5-94°.
Y2Cd3N4 crystallizes in the monoclinic C2/c space group. Y(1) is bonded to two equivalent N(1) and four equivalent N(2) atoms to form a mixture of edge and corner-sharing YN6 octahedra. The corner-sharing octahedral tilt angles are 9°. There is one shorter (2.51 Å) and one longer (2.55 Å) Y(1)-N(1) bond length. There are a spread of Y(1)-N(2) bond distances ranging from 2.37-2.54 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 4-coordinate geometry to one N(2) and three equivalent N(1) atoms. The Cd(1)-N(2) bond length is 2.30 Å. There are a spread of Cd(1)-N(1) bond distances ranging from 2.34-2.67 Å. In the second Cd site, Cd(2) is bonded in a linear geometry to two equivalent N(1) atoms. Both Cd(2)-N(1) bond lengths are 2.14 Å. There are two inequivalent N sites.
