Abstract Dibenzyldibromotin(IV) (2) promoted the ring-opening of 2-methyl-2-pyridyl-2,3-dihydrobenzo[d]thiazole heterocycle (1), with the activation of one C–Sn bond, to release toluene as coproduct. The resultant heteroleptic complex [Sn{L}BnBr2] (3), where {L}− = {SC6H4N(Me)C(C5H4N)}−, displayed a κ3-N,N′,S tridentate coordination pattern of the Schiff base. The 119Sn{1H} chemical shift is consistent with a hexacoordinate tin(IV) species in solution. Single-crystal X-ray studies at 293 K were carried out for the precursor 1 and for complex 3. In the crystal, the SnIV center in 3 displayed a distorted octahedral local geometry, with both bromo ligands in trans position. In the crystal, 1 and 3 displayed diverse intermolecular contacts; 3 was also studied by a Hirshfeld surface analysis.

二氢苯并噻唑杂环的反应性：含有三齿希夫配体的有机锡化合物的合成、分子和晶体结构

摘要 二苄基二溴化 (IV) (2) 促进了 2-甲基-2-吡啶基-2,3-二氢苯并[d]噻唑杂环 (1) 的开环，激活了一个 C-Sn 键，释放出甲苯作为副产品。合成的杂配复合物 [Sn{L}BnBr2] (3)，其中 {L}− = {SC6H4N(Me)C(C5H4N)}−，显示了 Schiff 碱的 κ3-N,N',S 三齿配位模式. 119Sn{1H} 化学位移与溶液中的六配位锡 (IV) 物质一致。在 293 K 下对前体 1 和配合物 3 进行了单晶 X 射线研究。在晶体中，3 中的 SnIV 中心显示出扭曲的八面体局部几何形状，两个溴配体都处于反位。在晶体中，1 和 3 表现出不同的分子间接触；3 还通过 Hirshfeld 表面分析进行了研究。
