The material structure described by YReN3 crystallizes in the monoclinic C2/c space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded to two equivalent N(2) and four equivalent N(3) atoms to form YN6 octahedra that share corners with six equivalent Re(1)N4 tetrahedra, edges with two equivalent Y(1)N6 octahedra, and edges with three equivalent Y(2)N6 pentagonal pyramids. In the second Y site, Y(2) is bonded to two equivalent N(1), two equivalent N(2), and two equivalent N(3) atoms to form distorted YN6 pentagonal pyramids that share corners with four equivalent Re(1)N4 tetrahedra, edges with three equivalent Y(1)N6 octahedra, and edges with two equivalent Re(1)N4 tetrahedra. Re(1) is bonded to one N(2), one N(3), and two equivalent N(1) atoms to form ReN4 tetrahedra that share corners with three equivalent Y(1)N6 octahedra, corners with two equivalent Y(2)N6 pentagonal pyramids, corners with two equivalent Re(1)N4 tetrahedra, and  an edgeedge with one Y(2)N6 pentagonal pyramid. The corner-sharing octahedral tilt angles range from 29-67°. There are three inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one Y(2) and two equivalent Re(1) atoms. In the second N site, N(2) is bonded in a distorted T-shaped geometry to one Y(1), one Y(2), and one Re(1) atom. In the third N site, N(3) is bonded to one Y(2), two equivalent Y(1), and one Re(1) atom to form a mixture of distorted corner and edge-sharing NY3Re tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
