[Et4N]2(u3-Se)Fe3(CO)9]與溴丙炔以莫耳數1：1於二氯甲烷反應，可分離出[Et4N][(u3-Se)Fe3(CO)9(u3-η1：η2：η3-C(O)C(H) =C = CH2)](Ia)。但是若將溴溴丙炔比例提高，除Ia外，另外可得(u3-Se)Fe3(CO)9-(u3-C(CH3) = CH)(Ⅱa)。Ia與[Cu(CH3CN)4]BF4於二氯甲烷中反應，可分離出IIa和SeFe2(CO)6(u3-C(CH3)=CHC(O))(Ⅲ)。若Ia與CF3SO3CH3反應，可分離出二种構形的(u3-Se)Fe3(CO)9(u3-η2:η1:η3-C(OCH3)(H)=C=CH2)[(IVa1)、(IVa2)]。
[Et4N]2(u3-Te)Fe3(CO)9]與溴丙炔已以1:1於二氯甲烷反應，可分離出[Et4N]2(u3-Te)Fe3(CO)9(u3-η:η:η-C(O)C(H)=C=CH2)](Ib)。若溶劑是甲基氰，且將溴丙炔比例提高，除了Ib外，另外可行另可行兩個蝴蝶形架構的化合物Te2Fe2(CO)6(CH=C=CH2)2(V)和Te2Fe2(CO)6(CH2C=CH)(CH=C=CH2)(VI)。Ib與[Cu(CH3CN)4]BF4於放二氯甲烷中反應，可得已知結構的Te2Fe3(CO)9。若Ib與CF3SO3CH3反應，可分離出一種構形之(u3-T3)Fe3(CO)9(u3-η:η:η-C(OCH3)C(H)=C=CH2)(IVb)。
K2TeO3H2O和Mn2(CO)10以莫耳數2:1於甲醇中加熱迴流，可得[TMBA][Te3Mn3(CO)10](VⅡ)，以莫耳數1:1混合反應時可得[PPN]2[Te2Mn3(CO)9](VⅢ)，以莫耳數1:2混合反應時可得[PPN]2[Te2Mn4(CO)12](IX)。IX於二甲烷中和CF3SO3CH3反應可得[PPN][Te2Mn4(CO)4Te(CH3)2](X)。
新化合物皆以X-ray繞射解析得知其結構，含有機配位基的化合物使用核磁共振譜儀輔助鑑定結構。

The reactions of [Et4N]2[(μ3-E)Fe3(CO)9] with propargyl bromide in CH2CI2 afford novel heterotetranuclear metal-(acylallenyl) complexes, [Et4N][(μ3-E)Fe3(CO)9(μ3η1:η1:η3-C(O)C(H)=C=CH2)](E=Se, Ia; E=Te, Ib), respectively.
When Ia is treated with [Cu(CH3CN)4]BF4, (μ3-Se)Fe3(CO)9(μ3-C(CH3)=CH)(IIa) and SeFe2(CO)6(μ3-C(CH3)=CHC(O))(III) are obtained.Whereas Ib reacts with [Cu(CH3CN)4]BF4，Te2Fe3(CO)9 is produced. Further reaftion of Ia with CH3SO3CF3 produces two rotational isomeers (E and Z forms), (μ3-Se)Fe3(CO)9(μ3-η2:η1:η3-C(OCH3)CH=C=CH2) (IVa1,IVa2). However, the reaction of Ib with CH3SO3CF3 forms (μ3-Te)Fe3(CO)9(μ3-η2:η1:η3-C(OCH3)CH=C=CH2) (IVb), with only one conformation (Z form).
The treatments of K2TeO3.H2O with Mn2(CO)10 in methanol, in different ratios, produce [Te4Mn3(CO)10]-(VII), [Te2Mn3(CO)9]2- (VIII), and [Te2Mn4(CO)12]2- (IX), respectively. The reaction of [Te2Mn4(CO)12]2- with CH3SO3CF3 forms the methylated product, [Te2Mn4(CO)12Mn(CO)4Te(CH3)2]- (X).
Complexes I-X are fully structurally characterized by X-ray analysis and spectroscopy methods. The reactivity and structural transformations of three new clusters are also studied and described.
