Hydrogen bond studies

Abstract
The crystal structure of RbH3(SeO3)2 has been investigated from three-dimensional single crystal neutron diffraction data obtained at room temperature. The asymmetric unit consists of an Rb+ ion, an HSeO3- ion and an H2SeO3 molecule.The SeO3-groups are connected to form a three-dimensional network via three almost linear O-H … O hydrogen bonds of lengths 2.599(2), 2.570(3) and 2.512(2) A. No disorder has been observed in the structure.
