The quest for high-energy-density materials (HEDMs) based on transition metal complexes is focused on low-coordinate species. High-coordinate analogues are extremely rare. Here, the first example of a highly energetic complex (HEC) with the highest coordination number of eight in 3d metal coordination chemistry is reported. Its structure was confirmed by single crystal X-ray diffraction. Its remarkably high stability has also been investigated.

高度稳定的八配位能量复合体

对基于过渡金属配合物的高能量密度材料（HEDM）的追求集中在低坐标物种上。高坐标类似物极为罕见。在此，报道了在3d金属配位化学中配位数最高的高能配合物（HEC）的第一个示例。通过单晶X射线衍射确认了其结构。还研究了其非常高的稳定性。
