dinuclear complexes of the type [(OC)4Mn(μ-PRR′)]2 [R = R′ = C6H4-4-Me (5), C6H3-3,5-Me2 (6), R/R′ = Ph/cHex (7), R = R′ = C6H4-4-NMe2 (8)] with poor to moderate yields. These manganese(I) complexes are only sparingly soluble or even nearly insoluble in hydrocarbons at room temperature. Planar four-membered Mn2P2 rings represent the central moiety with four carbonyl ligands at each manganese(I) atom
二级膦的金属化 HPRR' [R = R' = C6H4-4-Me, C6H3-3,5-Me2 (3), C6H4-4-NMe2 (4); R/R' = Ph/cHex] 与沸腾二甲苯(异构体混合物)中的 Mn2(CO)10,直到气态一氧化碳的释放停止,导致形成 [(OC)4Mn( μ-PRR')]2 [R = R' = C6H4-4-Me (5), C6H3-3,5-Me2 (6), R/R' = Ph/cHex (7), R = R' = C6H4-4-NMe2 (8)] 产率低至中等。这些锰 (I) 络合物在室温下仅微溶或什至几乎不溶于碳氢化合物。平面四元 Mn2P2 环代表在每个锰 (I) 原子上具有四个羰基配体的中心部分。P 键合取代基的空间需求影响 Mn-P 键长以及 P-Mn-P 键角。
