The interaction of 3,6-di-tert-butyl-o-benzoquinone (3,6-Q) with indium in toluene leads to the tris-o-semiquinolate derivative (3,6-SQ)(3)In (3,6-SQ - radical-anion of 3,6-Q). According to single-crystal X-ray diffraction analysis, this complex has a trigonal prismatic structure. Magnetic measurements revealed that the exchange interactions between odd electrons of the paramagnetic ligands in (3,6-SQ)(3)In are antiferromagnetic in character. The treatment of (3,6-SQ)(3)In with 2,2'-dipyridyl (Dipy) causes the displacement of one o-quinone ligand and the formation of the (3,6-SQ)In(Dipy)(3,6-Cat) (3,6-Cat - dianion of 3,6-Q) derivative containing mixed charged o-quinoid ligands. The reaction of InI with (3,6-SQ)K in THF solution is accompanied by a redox process and the potassium-indium(iii) catecholate derivative was obtained as a result. The oxidation of InI with 3,6-Q in THF produces the dimeric In(iii) iodo-catecholate complex [(3,6-Cat)(2)In·2THF]InI(2). The same derivative can be synthesized by the interaction of indium metal with a mixture of I(2) and 3,6-Q.
3,6-二叔丁基邻苯醌(3,6-Q)与铟在甲苯中的相互作用导致三-o-半醌衍生物(3,6-SQ)(3)In(3,6-SQ - 3,6-Q 的自由基阴离子)。根据单晶 X 射线衍射分析,该配合物具有三角棱柱结构。磁性测量表明,(3,6-SQ)(3)In 中顺磁配体的奇数电子之间的交换相互作用具有反铁磁性质。用 2,2'-联吡啶(Dipy)处理(3,6-SQ)(3)In 会导致一个邻醌配体的取代和形成(3,6-SQ)In(Dipy)(3,6-Cat)(3,6-Cat - 3,6-Q 的二价阴离子)衍生物,其中含有混合电荷的邻醌配体。InI 与(3,6-SQ)K 在 THF 溶液中的反应伴随着氧化还原过程,结果得到了钾-铟(iii)儿茶酸盐衍生物。3,6-Q 在 THF 中氧化 InI 生成二聚铟(iii)碘儿茶酸盐配合物[(3,6-Cat)(2)In·2THF]InI(2)。该衍生物也可以通过铟金属与 I(2)和 3,6-Q 的混合物相互作用合成。
