Two organic-inorganic tin chlorides, namely (CHNCl)SnCl (1) and (CHNCl)SnCl (2), were prepared valence state control using ,,','',''-pentamethyldiethylenetriamine as a structure-directing agent. The two compounds have zero-dimensional structures crystallized in non-centrosymmetric orthorhombic space group 2 and 222, respectively. In compound 1, the divalent tin ion forms a seesaw coordination configuration with four chloride ions, whereas in compound 2, the tetravalent tin ion forms an octahedral coordination configuration with six chloride ions. The two compounds show a moderate second-harmonic generation response under 1064 nm laser irradiation. Notably, compound 2 displays a bright orange luminescence with a photoluminescence quantum yield of 19.67%. Theoretical calculations were performed to gain insights into the optical properties of the two compounds.
使用五甲基二亚乙基三胺作为结构导向剂，通过价态控制制备了两种有机-无机氯化锡，即(CHNCl)SnCl（1）和(CHNCl)SnCl（2）。这两种化合物具有零维结构，分别在非中心对称的正交空间群2和222中结晶。在化合物1中，二价锡离子与四个氯离子形成跷跷板配位构型，而在化合物2中，四价锡离子与六个氯离子形成八面体配位构型。这两种化合物在1064nm激光照射下表现出适度的二次谐波产生响应。值得注意的是，化合物2发出亮橙色荧光，光致发光量子产率为19.67%。进行了理论计算以深入了解这两种化合物的光学性质。
