  Reactions of divalent metal salts of Co, Ni and Zn with 1,2-di(salicylaldimino-o-phenylthio)ethane (H2L1) and 1,2-di(naphthaldimino-o-phenylthio)ethane (H2L2), having N2O2S2 cores, and 1,2-di(O-salicylaldimino-o-hydroxyphenyl)ethane (H2L3), having a N2O4 core, have been explored. Out of the three ligands and the nine products obtained from the corresponding reactions, two ligands and seven products were crystallographically characterized. However, all the ligands and the products were characterized by analytical and spectral methods. Reaction of H2L1 and H2L2 with Co(II) salts results in oxidative cleavage of the C–S bond to produce a Co(III) product bound to two dissimilar tridentate ligands formed as a result of the cleavage. The reaction of H2L1 and H2L2 with Co(III)acac in the presence of methanolic NaOH also shows cleavage of the C–S bond to give compounds similar to those obtained by reacting H2L1 and H2L2 with Co(II) salts in the absence of additional external base. However, the reaction of Co(II) salt with H2L3 did not lead to any C–O bond cleavage; rather it produced an octahedral Co(II) complex of the hexadentate H2L3. Reactions of all these three ligands with Ni(II) salt resulted in octahedral complexes of the corresponding hexadentate ligands. In the case of Zn(II), while H2L3 with a N2O4 core resulted in an octahedral complex, H2L1 and H2L2, both with a N2O2S2 core, produced pseudo-octahedral complexes whose Zn–S bond lengths are rather long. The conformations of both the 5-membered and 6-membered chelate rings formed in the products were evaluated. The extent of distortion exhibited in the geometry of these octahedral complexes was computed and appropriately compared.

  对二价金属盐钴、镍和锌与具有N2O2S2核心的1,2-二（水杨醛亚胺-o-苯硫）乙烷（H2L1）和1,2-二（萘醛亚胺-o-苯硫）乙烷（H2L2）以及具有N2O4核心的1,2-二（O-水杨醛亚胺-o-羟基苯）乙烷（H2L3）的反应进行了研究。在三种配体和从相应反应中获得的九种产物中，两个配体和七种产物进行了晶体学表征。然而，所有的配体和产物均通过分析和光谱方法进行了表征。H2L1和H2L2与Co(II)盐的反应导致C–S键的氧化裂解，产生与两种不同的三齿配体结合的Co(III)产物。H2L1和H2L2与Co(III)acac在甲醇钠氢氧化物存在下的反应也显示出C–S键的裂解，产生与在没有额外外碱的情况下H2L1和H2L2与Co(II)盐反应所获得的化合物类似。然而，Co(II)盐与H2L3的反应并未导致任何C–O键的裂解，而是产生了一个具有六齿配体H2L3的八面体Co(II)复合物。所有这三种配体与Ni(II)盐的反应生成了相应的六齿配体的八面体络合物。在Zn(II)的情况下，虽然具有 核心的H2L3产生了一个八面体络合物，但具有 S2核心的H2L1和H2L2则产生了伪八面体络合物，其Zn–S键长相对较长。对产物中形成的五元环和六元环螯合物的构象进行了评估，并计算了这些八面体络合物几何结构的畸变程度并进行了适当的比较。
