The novel triphenyl adduct of 2-[(2,6-dimethylphenyl)amino]benzoic acid (HDMPA; 1), i.e., [SnPh3(DMPA)] (2), the dimeric tetraorganostannoxane [Ph2(DMPA)SnOSn(DMPA)Ph2]2 (3), and the monomeric adduct [SnPh2(DMPA)2] (4), where DMPA is monodeprotonated HDMPA, have been prepared and structurally characterized by means of IR, 1H-NMR, and 13C-NMR spectroscopy. The structures of 1 and 2 have been determined
2-[(2,6-二甲基苯基)氨基]苯甲酸(HDMPA; 1)的新型三苯基加合物,即[SnPh 3(DMPA)](2),二聚四有机锡氧烷[Ph 2(DMPA)SnOSn(DMPA) )Ph 2 ] 2(3)和单体加合物[SnPh 2(DMPA)2 ](4),其中DMPA是单去质子化的HDMPA,已通过IR,1 H-NMR和13 C进行了结构表征-NMR光谱。1和2的结构已经通过X射线晶体学确定。对1的单晶X射线衍射分析表明,不对称单元中有两个分子HD1和HD2构象不同,都形成了中心对称的二聚体,它们通过羧基O原子之间的H键相连。对2的X射线分析表明,该化合物具有五配位结构,其中含有与羧基基团配位的Ph 3 Sn。大量的CH / π相互作用和分子内H键稳定了1和2的结构,它们通过CH / π和π / π自组装-堆叠互动。发现Ph 3 Sn加合物2是一种有前景的抗分枝杆菌先导化合物,对结核分枝杆
