Abstract: EuSO4 was prepared by a dry way reaction for the first time as follows:EuCl2 (s)+HgSO4(s) EuSO4(s) 3×10-4Pa.Ar/773K.72h→EuSO4+HgCl2(g) was obtained, orthorhombic barite structure (Prima, Z=4), with a=838.69± 0.15pm, b=534.95±0.09pm, c=688.18±0.13pm. Atom positions of Eu,S and O were proposed, resulting in a set of calculated intensities coincided well with the observed.

Key words: EuSO4 synthesis, Crystal structure
