在2-甲基咪唑(η)存在下，通过[TpiPr2Mn(O)]2与过量的过氧化氢反应，合成了一种单核侧向过氧锰络合物TpiPr2Mn(ImMeH)(ImMeH)(ImMeH)。其X-射线结构清楚地证明了η-2-过氧化氢与咪唑基N-H官能团之间存在分子间氢键作用。络合物3稳定，呈绿色，不氧化三苯基膦和乙基乙烯基醚。
A mononuclear side-on peroxo managanese (III) complex, TpiPr2Mn(η2-O2)(imMeH) (3) was prepared by the reaction of [TpiPr2Mn(O)]2with excess amount of H2O2in the presence of 2-methylimidazole (imMeH). Its X-ray structure clearly demonstrated the involvement of intermolecular hydrogen bonding interaction between η2-peroxide and imidazolyl N–H functional group. Complex 3 was stable, green in color and unable to oxygenate triphenylphosphine and ethyl vinyl ether.
