The monoclinic structure of trirubidium hydrogen bis[tetraoxoselenate(2−)], Rb3H(SeO4)2, has been refined from neutron powder diffraction data collected at 4 K revealing the peculiarities of the so-called zero-dimensional hydrogen-bond network. The hydrogen bridge, with an O...O distance of 2.473 (4) Å, is non-linear [O—H...O 173 (2)°], with the H atom disordered between two symmetry-constrained positions of half occupancy [H...H 0.34 (3) Å]. The disorder might be static.
