摘要：

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