The compound described by Cs3W2N5 crystallizes in the tetragonal I4_1 space group. There are four inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 7-coordinate geometry to one N(1), one N(4), two equivalent N(3), and three equivalent N(2) atoms. In the second Cs site, Cs(2) is bonded in a 5-coordinate geometry to one N(1), two equivalent N(4), and two equivalent N(5) atoms. In the third Cs site, Cs(3) is bonded in a 8-coordinate geometry to two equivalent N(2), two equivalent N(3), two equivalent N(4), and two equivalent N(5) atoms. In the fourth Cs site, Cs(4) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded to one N(1), one N(5), and two equivalent N(3) atoms to form corner-sharing WN4 tetrahedra. In the second W site, W(2) is bonded to one N(2), one N(5), and two equivalent N(4) atoms to form corner-sharing WN4 tetrahedra. There are five inequivalent N sites. In the first N site, N(1) is bonded in a distorted rectangular see-saw-like geometry to one Cs(1), one Cs(2), one Cs(4), and one W(1) atom. In the second N site, N(2) is bonded in a 1-coordinate geometry to one Cs(3), one Cs(4), three equivalent Cs(1), and one W(2) atom. In the third N site, N(3) is bonded in a 2-coordinate geometry to one Cs(3), two equivalent Cs(1), and two equivalent W(1) atoms. In the fourth N site, N(4) is bonded in a distorted linear geometry to one Cs(1), one Cs(3), two equivalent Cs(2), and two equivalent W(2) atoms. In the fifth N site, N(5) is bonded in a 2-coordinate geometry to one Cs(3), two equivalent Cs(2), one W(1), and one W(2) atom. is represented by the CIF card [CIF]
