The structure described by CuCrZrS4 crystallizes in the orthorhombic Pmmn space group. Zr(1) is bonded to two equivalent S(1), two equivalent S(2), and two equivalent S(3) atoms to form ZrS6 octahedra that share edges with two equivalent Zr(1)S6 octahedra, edges with four equivalent Cr(1)S6 octahedra, and edges with two equivalent Cu(1)S6 pentagonal pyramids. Cr(1) is bonded to one S(2), one S(3), and four equivalent S(1) atoms to form CrS6 octahedra that share corners with three equivalent Cu(1)S6 pentagonal pyramids, edges with two equivalent Cr(1)S6 octahedra, edges with four equivalent Zr(1)S6 octahedra, and  an edgeedge with one Cu(1)S6 pentagonal pyramid. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form distorted CuS6 pentagonal pyramids that share corners with six equivalent Cr(1)S6 octahedra, edges with two equivalent Cr(1)S6 octahedra, and edges with four equivalent Zr(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 5-7°. In the second Cu site, Cu(2) is bonded in a 6-coordinate geometry to two equivalent S(3) and four equivalent S(1) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded to one Zr(1), two equivalent Cr(1), one Cu(1), and one Cu(2) atom to form a mixture of distorted edge and corner-sharing SZrCr2Cu2 trigonal bipyramids. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to two equivalent Zr(1), one Cr(1), and one Cu(1) atom. In the third S site, S(3) is bonded in a rectangular see-saw-like geometry to two equivalent Zr(1), one Cr(1), and one Cu(2) atom. is represented by the CIF file [CIF]
