General description
树突锶是锶金属的一种形式，具有独特的树状或分支的形态。它通常通过电沉积制备。树突锶是一种银白色金属，与水和氧气的反应活性高，在空气中容易失去光泽。它具有多种重要的物理性质，包括769 °C的熔点和 2.54 g/cm3的密度。
Application
树突锶可用于津特尔相 SrSn3Sb4 的固态合成，它具有一个 30 元环的阴离子通道骨架。它也可用于制备铌酸钾锶（Sr2KNb5O15，SKN），SKN 非常适合用于热电传感器和各种电光装置。
树突锶有多重种重要用途，包括作为合金的成分，作为烟火设备的材料，作为铁氧体磁铁生产的试剂，以及作为半导体生产中的掺杂剂。

Redox-inactive metals are found in biological and heterogeneous water oxidation catalysts, but, at present, their roles in catalysis are not well understood. Here, we report a series of high-oxidation-state tetranuclear-dioxido clusters comprising three manganese centres and a redox-inactive metal (M).
