The material structure described by RbLi2Cr2(BO3)3 crystallizes in the monoclinic P2/c space group. Rb(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(5) atoms. Li(1) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form distorted LiO4 trigonal pyramids that share corners with two equivalent Cr(1)O6 octahedra,  a cornercorner with one Li(1)O4 trigonal pyramid, and  an edgeedge with one Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-75°. Cr(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form distorted CrO6 octahedra that share corners with two equivalent Li(1)O4 trigonal pyramids, edges with two equivalent Cr(1)O6 octahedra, and  an edgeedge with one Li(1)O4 trigonal pyramid. 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 4-coordinate geometry to one Rb(1), two equivalent Cr(1), and one B(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Rb(1), one Li(1), one Cr(1), and one B(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Li(1), two equivalent Cr(1), and one B(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Li(1), one Cr(1), and one B(2) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to two equivalent Rb(1), two equivalent Li(1), and one B(2) atom. is represented by the CIF file [CIF]
