Tb(HSO)(SO) - a green emitting hydrogensulfate sulfate with second harmonic generation response.

Recently, sulfates have attracted attention as materials for non-linear optical applications. This compound class is extended by Tb(HSO)(SO), which is solvothermally synthesised from TbO and sulfuric acid. The compound crystallises in the non-centrosymmetric space group P2 (Z = 2, a = 665.

RE[B(SO)] (RE = Y, La-Nd, Sm, Eu, Tb-Lu): a silicate-analogous host structure with weak coordination behaviour.

The rare earth borosulfates RE2[B2(SO4)6] with RE = Y, La-Nd, Sm, Eu and Tb-Lu were synthesised under solvothermal conditions starting from the metal chlorides (Pr, Nd, Eu), the metal oxides (Y, La, Ce, Sm, Tb, Dy, Er, Tm, Lu), or the metal powders (Ho, Yb). They crystallize isotypically with Gd2[B2(SO4)6] in space group C2/c (Z = 4, a = 1346.9(3)-1379.
