The Front Cover shows the reversible H2 heterolytic splitting/H2 production by nickel diazadiphosphacyclooctane complexes [Ni(PR12NR22)2]2+ in which the nickel(II) dihydrogen complex so far remained the undetected intermediate. The use of a particular bait (para-hydrogen) allowed bringing this species to light with the help of the specially equipped submarine (PArtially NEgative Line experiments in NMR). The chosen set of R1, R2 substituents stabilizes nickel(II) hydride products, preventing their irreversible conversion into Ni(0) complexes. The authors thank Ekaterina Gulyaeva for creating the cover design. More information can be found in the Full Paper by K. L. Ivanov, N. V. Belkova and co-workers.

封面:镍 (II) 二氢和氢化物配合物作为二氮杂二磷环辛烷镍配合物分裂 H2 的中间体 (Eur. J. Inorg. Chem. 41/2021)

封面显示了由二氮杂二磷环辛烷镍配合物 [Ni(P R1 2 N R2 2 ) 2 ] 2+可逆的 H 2异裂分裂/H 2生产,其中镍 (II) 二氢配合物迄今为止仍然是未检测到的中间体。在特殊装备的潜艇的帮助下(核磁共振中的部分负线实验),使用特定的诱饵(副氢)可以使该物种曝光。选定的一组 R 1 , R 2取代基稳定镍 (II) 氢化物产物,防止它们不可逆地转化为 Ni(0) 配合物。作者感谢 Ekaterina Gulyaeva 创建封面设计。更多信息可以在 K. L. Ivanov、N. V. Belkova 和同事的全文中找到。
