scorpions, the authors simulate the structure and the coordination ability of a ligand that appears as the shadow of this animal. The claws of the animal are pyrazolyl rings, the binding sites of this ligand to metallic centers. The image also contains the metallic compounds used to generate dinuclearcomplexes or zigzag or helical polymers.
卡斯蒂利亚-拉曼恰-IRICA 大学的 Felix Jalon 和 Blanca Manzano 小组受邀为本期封面。作者通过两只蝎子结合形成的一种奇怪动物的封面图片,模拟了一种配体的结构和协调能力,该配体表现为这种动物的影子。动物的爪子是吡唑环,这是配体与金属中心的结合位点。该图像还包含用于生成双核配合物或锯齿形或螺旋形聚合物的金属化合物。

unsuitable for this analysis. Of the structurally characterized silver(I) complexes, that with L22 showed an unusual trans-spanning chelating coordination mode to silver. At the same time the ligand was also bound to a second silver center giving rise to a cyclic supramolecular isomer with a 22-membered metallacycle. The complex of L34 also gave a cyclic dication but with a remarkable 28-membered metallacycle
