The structure described by Co3B7O13Cl crystallizes in the trigonal R3c space group. Co(1) is bonded to one O(1), one O(2), one O(4), one O(5), and one Cl(1) atom to form CoClO4 trigonal bipyramids that share corners with three equivalent B(1)O4 tetrahedra, corners with four equivalent B(3)O4 tetrahedra, and corners with two equivalent Co(1)ClO4 trigonal bipyramids. There are three inequivalent B sites. In the first B site, B(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form BO4 tetrahedra that share corners with two equivalent B(1)O4 tetrahedra, corners with three equivalent B(3)O4 tetrahedra, and corners with three equivalent Co(1)ClO4 trigonal bipyramids. In the second B site, B(2) is bonded in a trigonal planar geometry to three equivalent O(4) atoms. In the third B site, B(3) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form BO4 tetrahedra that share corners with three equivalent B(1)O4 tetrahedra and corners with four equivalent Co(1)ClO4 trigonal bipyramids. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Co(1), one B(1), and one B(3) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Co(1), one B(1), and one B(3) atom. In the third O site, O(3) is bonded in a trigonal non-coplanar geometry to three equivalent B(1) atoms. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Co(1), one B(2), and one B(3) atom.
