The dimeric, tetranuclear manganese(II)‐substituted sandwich‐type phosphotungstate complex has been synthesized in high yield using a straightforward one‐pot synthesis by reacting commercially available H 3 [PW 12 O 40 ] with MnCl 2 . The complex has been characterized by single‐crystal X‐ray structure analysis. The complex is oxidatively and solvolytically stable and has been used as a heterogeneous catalyst in the efficient, selective aerobic epoxidation of styrene, cyclohexene and cis ‐cyclooctene.
