Hg2(SeO3)(SO4): the first sulfate selenite with large birefringence explored from d10transition metal compounds

Abstract: Exploration of new birefringent materials in d10 transition metal sulfate selenite system results three new compounds, namely, Hg2(SeO3)(SO4), La2Hg3(SeO3)4(SO4)2(H2O)2 and Ag2Cd(Se2O5)(Se0.3S0.7O4), by mild hydrothermal methods. Hg2(SeO3)(SO4) shows a 3D structure...

“…The underestimate for CaYF(SeO 3 ) 2 can be ascribed to the disordered structural model, which were often found in literatures. [46][47][48] For the ordered Y 3 F(SeO 3 ) 4 , the theoretical value is close to the experimental result.…”

“…CaYF-(SeO 3 ) 2 has a large birefringence with different refractive indices on the 100, 010 and 001 axes, with the refractive indices following the order n 100 > n 010 > n 001 . The birefringence (Δn) is 0.138@532 nm and 0.127@1064 nm respectively, which are comparable with those of Hg 2 (SeO 3 )(SO 4 ) (0.133@532 nm and 0.126@1064 nm) [46] (Figure S11a). Combined with its wide band gap, CaYF(SeO 3 ) 2 can be a potential UV birefringent material.…”

“…The most pivotal structural feature of Hg 3 (SeO 3 ) 2 (SO 4 ) is the spatial arrangement of unique [Hg 6 O 8 (SeO 3 ) 4 ] ∞ layers, promoting the formation of the noncentrosymmetric structure and may contribute to good optical properties. Remember the Hg 2 (SeO 3 )(SO 4 ) reported by Mao et al, 54 which contains the same basic building blocks (Hg 2+ -based polyhedra, SeO 3 , and SO 4 ) as Hg 3 (SeO 3 ) 2 (SO 4 ), but crystallizes in a centrosymmetric space group. Therefore, the spatial arrangement of basic building blocks is critical for constructing the symmetry of structures, which facilitates the exploration of the arrangement mechanism of the two crystals.…”

“…To increase the success rate of NCS structures, the d 10 TM cation Ag + was chosen to balance the charge due to its large polar displacement. 28,[45][46][47][48] After an extensive survey, we found that no silver tellurites with the fluorine element have been reported yet. Our efforts in the silver-tellurite-fluorine system successfully result in the first examples of silver fluorotellurites and the first silver fluoride tellurite, namely, AgTeO 2 F and Ag 2 (TeO 2 F 2 ), and Ag 3 F 3 (TeF 6 ) (TeO 2 ) 12 .…”
