The crystal structure described by Rb3InO3 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent Rb sites. In the first Rb site, Rb(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form distorted RbO4 trigonal pyramids that share corners with five equivalent In(1)O4 tetrahedra and  an edgeedge with one Rb(1)O4 trigonal pyramid. In the second Rb site, Rb(2) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. In the third Rb site, Rb(3) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. In(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form InO4 tetrahedra that share corners with five equivalent Rb(1)O4 trigonal pyramids and  an edgeedge with one In(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 7-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), two equivalent Rb(3), and one In(1) atom. In the second O site, O(2) is bonded in a 6-coordinate geometry to one Rb(1), one Rb(3), two equivalent Rb(2), and two equivalent In(1) atoms. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Rb(1), one Rb(2), two equivalent Rb(3), and one In(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
