Sn₃B₁₀O₁₇Cl₂ Achieving Birefringence Enhancement by Stereochemical Activity Lone Pair

Abstract

Sn3B10O17Cl2 was successfully obtained for the first time under the sealed environment and crystallized in the space group Pbcn belonging to the orthorhombic system, which is featured by the fundamental building blocks [B5O11] that are linked to construct a three-dimensional framework with Cl and Sn atoms located inside and at the edge of the channel to balance the charge. Moreover, the optical performance measurement shows that Sn3B10O17Cl2 owns a cutoff edge of about 280 nm. Theoretical study indicates its large optical anisotropy with the birefringence 0.125@546 nm; meanwhile, the structure–performance relationships were analyzed by the first-principle calculation.

Na4[B6O9 (OH)3](H2O) Cl: A Deep-Ultraviolet Transparent Nonlinear Optical Borate Chloride with {[B6O9 (OH)3]3–}∞ Chains

“…After 697.1 °C, the consistent mass loss is assigned to the volatilization of boron oxide. The thermal decomposition behavior of this compound is similar to the decomposition of borates previously reported, like LiNaB 6 O 9 F 2 and Sn 3 B 10 O 17 Cl 2 …”

“…35 In addition, about ninety-two borate halides have been reported until now (Table S5 borates previously reported, like LiNaB 6 O 9 F 2 59 and Sn 3 B 10 O 17 Cl 2 . 60 The IR spectra and peak assignments of the Na 4 [B 6 O 9 (OH) 3 ](H 2 O) Cl are depicted in detail in Figure S6 and Table S6, and the assignment of the related absorption peaks are comparable with those of the reported borates. 49,56,60 The UV−vis-NIR diffuse reflectance spectra (Figure 2 A power SHG signal measurement was obtained from the Kurtz−Perry method under a 1064 nm laser irradiation.…”

Ultraviolet Crystal with Strong Optical Nonlinearity by Creating Halogen-Centered Secondary Building Blocks

“…When combining the π- and non-π-conjugated groups, abundant sterling materials with polymerized or multiple NLO-active genes have emerged, such as KBe 2 BO 3 F 2 with [Be 2 BO 3 F 2 ], LiB 3 O 5 with [B 3 O 7 ], AB 4 O 6 F with [B 4 O 8 F] (A = NH 4 and Cs), , MB 5 O 7 F 3 (M = Ca and Sr) with [B 5 O 9 F 3 ], , and C­(NH 2 ) 3 SO 3 F with [C­(NH 2 ) 3 ] and [SO 3 F] . Likewise, the FBB [B 5 O 11 ] composed of three [BO 3 ] and two [BO 4 ] units is also a common ultraviolet gene; − however, to the best of our knowledge, the crystals with FBB [B 5 O 11 ] have not exhibited appreciable linear and NLO performance due to their inadequate structures.…”
