The structure described by KReN2 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to two equivalent N(1), two equivalent N(3), and four equivalent N(2) atoms. In the second K site, K(2) is bonded in a 5-coordinate geometry to one N(1), two equivalent N(2), and two equivalent N(3) atoms. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded to two equivalent N(2) and two equivalent N(3) atoms to form corner-sharing ReN4 tetrahedra. In the second Re site, Re(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing ReN4 tetrahedra. There are three inequivalent N sites. In the first N site, N(1) is bonded in a 5-coordinate geometry to one K(2), two equivalent K(1), and two equivalent Re(2) atoms. In the second N site, N(2) is bonded in a distorted linear geometry to one K(2), two equivalent K(1), one Re(1), and one Re(2) atom. In the third N site, N(3) is bonded in a distorted linear geometry to two equivalent K(1), two equivalent K(2), and two equivalent Re(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
