In order to reveal the integrated effect of inorganic lattice structure disturbances and chiral ligands on the structure of tin halide hybrid materials, we show the synthesis, crystal growth, dissolution recrystallization structural transformation (DRST), optical properties, energy band structure, and nonlinear optical properties of a class of chiral tin bromide R/S-2-mpip[SnBr3]Br (2-mpip is 2-methylpiperazinium) and R/S-2-mpipSnBr6 for the first time. The formation of R/S-2-mpipSnBr6 in solution was interestingly caused by irreversible DRST of R/S-2-mpip[SnBr3]Br. The second-harmonic generation response of the new phase R-2-mpipSnBr6 is significantly enhanced compared to that of the initial phase R-2-mpip[SnBr3]Br. These structural transformations of chiral tin bromides reflect, to some extent, the DRST commonality of the tin halide family induced by oxidation and serve as a starting point for investigating the structural chirality and asymmetry of chiral metal hybrid halides.

氧化诱导溶解再结晶结构转变策略增强杂化手性溴化锡单晶的非线性光学效应
为了揭示无机晶格结构扰动和手性配体对卤化锡杂化材料结构的综合影响，我们展示了卤化锡杂化材料的合成、晶体生长、溶解重结晶结构转变（DRST）、光学性质、能带结构和非线性光学。首次研究了一类手性溴化锡R / S -2-mpip[SnBr 3 ]Br（2-mpip为2-甲基哌嗪鎓）和R / S -2-mpipSnBr 6的性质。有趣的是，溶液中R / S -2-mpipSnBr 6的形成是由R / S -2-mpip[SnBr 3 ]Br 的不可逆DRST引起的。与初始相R -2-mpip[SnBr 3 ]Br相比，新相R -2-mpipSnBr 6的二次谐波产生响应显着增强。手性溴化锡的这些结构转变在一定程度上反映了氧化诱导的卤化锡家族的DRST共性，并可作为研究手性金属杂化卤化物的结构手性和不对称性的起点。
