K4V5CuO15Cl crystallizes in the tetragonal P4 space group. K(1) is bonded in a 8-coordinate geometry to one O(2), one O(3), two equivalent O(1), three equivalent O(4), and one Cl(1) atom. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form VO4 tetrahedra that share  a cornercorner with one Cu(1)ClO4 square pyramid,  a cornercorner with one V(1)O4 tetrahedra, and  a cornercorner with one V(2)O5 trigonal bipyramid. In the second V site, V(2) is bonded to one O(5) and four equivalent O(3) atoms to form distorted corner-sharing VO5 trigonal bipyramids. Cu(1) is bonded to four equivalent O(1) and one Cl(1) atom to form distorted CuClO4 square pyramids that share corners with four equivalent V(1)O4 tetrahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to two equivalent K(1), one V(1), and one Cu(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent K(1) and two equivalent V(1) atoms. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one K(1), one V(1), and one V(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to three equivalent K(1) and one V(1) atom. In the fifth O site, O(5) is bonded in a single-bond geometry to one V(2) atom. Cl(1) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Cu(1) atom.
