Abstract A discrete class of metal–oxygen clusters, Polyoxometalates (POMs) have received tremendous attention for their convenient shapes, sizes, compositions and structural diversities. Amongst their numerous advantages, one that stands out is their ability to be modified at molecular level, giving rise to second, third and even fourth generation materials. In this regard, Transition Metal Substituted Polyoxometalates (TMSPOMs), a subclass of POMs, are extremely relevant even today. Amongst, Mn substituted POMs (Mn-POMs) visibly attract significant attention due to variable oxidation states, redox and magnetic properties. Mn-POMs, themselves comprise an entire arena of inorganic building blocks with large assortments of morphologies, structural flexibility and functionality. Herein, we have compiled the different syntheses, strategies for modification, characterizations as well as diverse applications of Mn containing Keggin and Dawson POMs. We have also catalogued the available literature on the synthesis and applications of Mn-POMs, modified via functionalization as well as supporting. Our intension behind this review is to provide readers, in-depth insights, and a fundamental, representative and comprehensive overview of the work done so far in this emerging field, emphasizing on industrially viable catalytic systems. Thus, the article would appeal not only to POMs community but also to Crystallographers, electrochemists as well as physical chemists.

改性锰取代 POM：合成策略、应用的结构多样性

摘要 多金属氧酸盐 (POM) 是一类离散的金属氧簇，因其方便的形状、尺寸、组成和结构多样性而受到极大关注。在它们众多的优势中，最突出的是它们能够在分子水平上进行改性，从而产生第二代、第三代甚至第四代材料。在这方面，过渡金属取代的多金属氧酸盐 (TMSPOM) 是 POM 的一个子类，即使在今天也非常重要。其中，Mn 取代的 POM（Mn-POM）由于可变的氧化态、氧化还原和磁性而明显吸引了大量关注。Mn-POMs 本身包含一个完整的无机构建块领域，具有多种形态、结构灵活性和功能性。在这里，我们编译了不同的综合，包含 Keggin 和 Dawson POM 的 Mn 的改性、表征以及各种应用的策略。我们还对有关 Mn-POM 合成和应用的可用文献进行了编目，这些文献通过功能化和支持进行了修改。我们在这篇评论背后的意图是为读者提供深入的见解，以及迄今为止在这个新兴领域所做的工作的基本、有代表性和全面的概述，强调工业上可行的催化系统。因此，这篇文章不仅会吸引 POM 社区，还会吸引晶体学家、电化学家和物理化学家。通过功能化和支持进行修改。我们在这篇评论背后的意图是为读者提供深入的见解，以及迄今为止在这个新兴领域所做的工作的基本、有代表性和全面的概述，强调工业上可行的催化系统。因此，这篇文章不仅会吸引 POM 社区，还会吸引晶体学家、电化学家和物理化学家。通过功能化和支持进行修改。我们在这篇评论背后的意图是为读者提供深入的见解，以及迄今为止在这个新兴领域所做的工作的基本、有代表性和全面的概述，强调工业上可行的催化系统。因此，这篇文章不仅会吸引 POM 社区，还会吸引晶体学家、电化学家和物理化学家。
