The structure described by Rb4Hf3S14 crystallizes in the monoclinic C2/c space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 10-coordinate geometry to one S(1), one S(3), one S(4), two equivalent S(5), two equivalent S(7), and three equivalent S(6) atoms. In the second Rb site, Rb(2) is bonded in a 10-coordinate geometry to one S(4), one S(5), one S(6), one S(7), two equivalent S(1), two equivalent S(2), and two equivalent S(3) atoms. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded to one S(2), one S(3), one S(4), one S(6), one S(7), and two equivalent S(5) atoms to form distorted HfS7 pentagonal bipyramids that share  a cornercorner with one S(7)Rb3HfS trigonal bipyramid,  an edgeedge with one Hf(1)S7 pentagonal bipyramid, and  a faceface with one Hf(2)S8 hexagonal bipyramid. In the second Hf site, Hf(2) is bonded to two equivalent S(1), two equivalent S(2), two equivalent S(3), and two equivalent S(4) atoms to form distorted HfS8 hexagonal bipyramids that share corners with two equivalent S(7)Rb3HfS trigonal bipyramids and faces with two equivalent Hf(1)S7 pentagonal bipyramids. There are seven inequivalent S sites. In the first S site, S(2) is bonded in a 5-coordinate geometry to two equivalent Rb(2), one Hf(1), one Hf(2), and one S(7) atom. In the second S site, S(3) is bonded in a 2-coordinate geometry to one Rb(1), two equivalent Rb(2), one Hf(1), one Hf(2), and one S(6) atom. In the third S site, S(4) is bonded in a 5-coordinate geometry to one Rb(1), one Rb(2), one Hf(1), one Hf(2), and one S(1) atom. In the fourth S site, S(5) is bonded in a 5-coordinate geometry to one Rb(2), two equivalent Rb(1), and two equivalent Hf(1) atoms. In the fifth S site, S(6) is bonded in a 6-coordinate geometry to one Rb(2), three equivalent Rb(1), one Hf(1), and one S(3) atom. In the sixth S site, S(7) is bonded to one Rb(2), two equivalent Rb(1), one Hf(1), and one S(2) atom to form distorted SRb3HfS trigonal bipyramids that share  a cornercorner with one Hf(2)S8 hexagonal bipyramid,  a cornercorner with one Hf(1)S7 pentagonal bipyramid, and  an edgeedge with one S(7)Rb3HfS trigonal bipyramid. In the seventh S site, S(1) is bonded in a 5-coordinate geometry to one Rb(1), two equivalent Rb(2), one Hf(2), and one S(4) atom. is represented by the CIF file [CIF]
