The Cover Feature shows four reactive metal–hydroxo, metal–alkoxo, and metal–nitrato complexes. These and other M–O–X species are capable oxidants that can abstract hydrogen atoms from C–H and O–H bonds and can model the possible intermediates present in various enzymatic and synthetic catalytic cycles. They exemplify the variety of structures that can be involved in oxidation processes, aside from the more conventional metal–oxo species. More information can be found in the Microreview by P. Pirovano and A. R. McDonald.

封面人物：合成高效价的M–O–X氧化剂（Eur。J. Inorg。Chem。5/2018）

封面特征显示了四种反应性金属-羟基，金属-烷氧基和金属-硝基络合物。这些和其他M–O–X物质是能够从C–H和O–H键中提取氢原子的氧化剂，并且可以模拟各种酶催化和合成催化循环中可能存在的中间体。除了更传统的金属-氧代物种外，它们还举例说明了氧化过程中可能涉及的各种结构。可以在P. Pirovano和AR McDonald撰写的Microreview中找到更多信息。
