在空气存在下，(L2MnIII2(μ-O)(μ-MeCO2)2](CIO4)2 与 Na2HPO4、(NH4)3VO4 或 Na2HAsO4 在水溶液（pH 约 9）中反应，添加 NaBr 后，生成深红色晶体 [L3MnIV3(μ2-O)3(μ3-XO4)]Br3(X = P、As 或 VV；L = 1,4,7-三氮杂环壬烷）；通过 X 射线晶体学对 µ-磷酸复合物进行表征表明存在离散的三聚阳离子 [L3MnIV3(µ-O)3(µ-PO4)]3+，其中三个 MnIV 中心位于由三个 µ2-氧桥和一个 µ3-PO4 桥连接的扭曲八面体 fac-N3O3 供体组中。
The reaction of (L2MnIII2(µ-O)(µ-MeCO2)2](CIO4)2 with Na2HPO4, (NH4)3VO4, or Na2HAsO4 in aqueous solution (pH ca. 9) in the presence of air yields, upon addition of NaBr, deep red crystals of [L3MnIV3(µ2-O)3(µ3-XO4)]Br3(X = P, As, or VV; L = 1,4,7-triazacyclononane); characterization of the µ-phosphato complex by X-ray crystallography showed the presence of discrete trimeric cations [L3MnIV3(µ-O)3(µ-PO4)]3+ where three MnIV centres are in a distorted octahedral fac-N3O3 donor set connected by three µ2-oxo bridges and a µ3-PO4 bridge.
