4-triazole-5-thione (HL4). Compounds 1–4 were characterized by elemental analysis, IR spectra and their structures were determined by single-crystal X-ray diffraction methods. Complexes 1–3 show similar structures containing a Sn4O4 ladder skeleton in which each of the exo tin atoms is bonded to the N atom of a corresponding thione-form deprotonated ligand. Complex 4 shows a mononuclear structure in which the tin atom
四种新的有机锡配合物,即[(Bu 2 Sn)2 O(EtO)(L1)] 2(1),[(Bu 2 Sn)2 O(EtO)(L2)] 2(2),[(Bu 2 Sn)2 O(EtO)(L3)] 2(3)和[Ph 3 Sn(L4)]·0.5H 2 O(4),是通过Bu 2 SnO和Ph 3 SnOH与4-苯基亚氨基氨基反应制得的。3-甲基1,2,4-三唑-5-硫酮(HL1),4-糠醛亚氨基-3-甲基-1,2,4-三唑-5-硫酮(HL2),4-(2-噻吩亚氨基)- 3-乙基1,2,4-三唑-5-硫酮(HL3)和4-(3,5-二-叔丁基水杨基亚氨基)-3-乙基-1,2,4-三唑-5-硫酮(HL4)。化合物1 - 4进行了表征通过元素分析,红外光谱和其结构经单晶X-射线衍射方法测定的。配合物1 - 3示出具有Sn类似结构4 ø 4,其中每个所述的梯子骨架外的锡原子键合到相应的硫酮形式配体去质子化的N原子
