The material described by RbLi2Co2(BO3)3 crystallizes in the monoclinic P2/c space group. Rb(1) is bonded to two equivalent O(2), two equivalent O(3), two equivalent O(4), two equivalent O(5), and four equivalent O(1) atoms to form distorted RbO12 cuboctahedra that share corners with two equivalent Rb(1)O12 cuboctahedra, corners with two equivalent Co(1)O4 tetrahedra, edges with two equivalent Rb(1)O12 cuboctahedra, edges with two equivalent Li(1)O4 tetrahedra, edges with four equivalent Co(1)O4 tetrahedra, and faces with two equivalent Li(1)O4 tetrahedra.

There are two inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(5) and two equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Rb(1), one Co(1), and one B(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Rb(1), one Li(1), one Co(1), and one B(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Rb(1), one Li(1), one Co(1), and one B(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Rb(1), one Li(1), one Co(1), and one B(2) atom.
