and X-ray structure of cobalt(III) species, [Co(L1)Cl](PF6)2, is also reported. In situ reaction of L1 with copper(II) as a metal template in the presence of formaldehyde and the carbon acid nitroethane together with triethylamine (as base) led to macrocycle ring closure to yield [Cu(L2)Cl]PF6 (where L2 = 6,13-dimethyl-6-nitro-13-(pyridin-2-yl)-1,11-dithia-4,8-diazacyclotetradecane) whose X-ray structure
新的潜在五齿配体 2,2'-(2-methyl-2-(pyridin-2-yl)propane-1,3-diyl)bis(sulfanediyl)diethanamine (L1) 的合成,含有两个硫醚硫,描述了两个 -NH2 胺和一个吡啶基氮杂原子。L1 与氯化铜 (II) 和添加六氟磷酸根阴离子的反应导致混合阴离子复合物 Cu2(L1)2Cl(PF6)3 的分离。还报告了钴 (III) 物种 [Co(L1)Cl](PF6)2 的合成和 X 射线结构。在甲醛和碳酸硝基乙烷以及三乙胺(作为碱)存在下,L1 与作为金属模板的铜(II)的原位反应导致大环闭环生成 [Cu(L2)Cl]PF6(其中 L2 = 6,13-二甲基-6-硝基-13-(pyridin-2-yl)-1,11-dithia-4,
