摘要
[Et4N]2[SeFe3(CO)9]與Cu+ 試劑的反應，不同的Cu+ 來源，可生成不同的產物：與[Cu(CH3CN)4]BF4的反應可生成{[SeFe3(CO)9]2 -Cu}3-，與CuOAc反應可生成{[SeFe3(CO)9]2Cu2(μ-OAc)}3-。另外混合dppm與dppe於[SeFe3(CO)9]2-與[Cu(CH3CN)4]BF4的反應中，利用反應溶劑以及反應物比例的不同，可生成一系列含Cu片段的化合物(μ5-Se)Fe3(CO)9Cu2(μ-dppm)(L) (L = CH3CN, THF)、SeFe3(CO)9Cu2 -(μ-dppe)、{[SeFe3(CO)9]2Cu2(μ-dppe)}2-和{[SeFe3(CO)8]Cu2(μ-dppm) -(μ-dppm)}。 以Se powder和Mn2(CO)10於鹼性溶液中在室溫下反應，不同的濃度及反應時間，可得到不同的結果：於0.9 M KOH下以Se: Mn = 1: 1比例反應一小時，可得到[Se10Mn6(CO)18]4-；若將KOH濃度提高至4 M，則可得到[Se2Mn3(CO)9]2-。以Se: Mn = 10: 6比例，於0.9 M KOH和4 M KOH濃度下反應一小時，皆可得到[Se10Mn6(CO)18]4-；若延長反應時間至十天，於0.9 M KOH下可得[Se5Mn4(CO)12]2-，而於4 M KOH下可得到[Se6Mn6(CO)18]4-，二者皆為新型結構之化合物。

The reactions of [Et4N]2[SeFe3(CO)9] with different Cu+ reagents resulted in different products. When [Et4N]2[SeFe3(CO)9] reacted with [Cu(CH3CN)4]BF4 and CuOAc, {[SeFe3(CO)9]2Cu}3- and {[SeFe3 -(CO)9]2Cu2(μ-OAc)}3- were obtained, respectively. On the other hand, if [SeFe3(CO)9]2- was treated with [Cu(CH3CN)4]BF4/dppm or dppe in varied ratios and different solvents, a series of copper-incorporated E-Fe clusters: (μ5-Se)Fe3(CO)9Cu2(μ-dppm)(L) (L = CH3CN, THF), SeFe3 -(CO)9Cu2(μ-dppe), {[SeFe3(CO)9]2Cu2(μ-dppe)}2-, and {[SeFe3(CO)8] -Cu2(μ-dppm)(μ-dppm)} were produced. The reactions of Se powder with Mn2(CO)10/KOH/MeOH solution in varied reaction condition were systematically studied. While Se powder reacted with 0.5 eq Mn2(CO)10 in 0.9 M KOH/MeOH solution for 1 hr to produce [Se10Mn6(CO)18]4-, the similar reaction in 4 M KOH/MeOH solution gave [Se2Mn3(CO)9]2-. In the case of Se: Mn in the ratio of 10: 6, the reaction of Se with Mn2(CO)10 in 0.9 M or 4 M of KOH/MeOH for 1 hr led to formation of the new complex [Se10Mn6(CO)18]4-. However, if the reactions proceeded for ten days in 0.9 M and 4 M of KOH/MeOH solutions for ten days, [Se5Mn4(CO)12]2- and [Se6Mn6(CO)18]4- were obtained, both of which represent novel types of complexes in the Se-Mn-CO system.
