[PhCH2NMe3]2 [Te4Fe5(CO)14] has been isolated and structrually characterized by ingle-crystal X-ray diffraction and spectroscopic methods. Treatment of [Te6Fe8(CO)24]2- with BrCH2CH2Br, BrCH2CH2Cl or ClCH2CH2CH2Cl in THF produces [BrTe2Fe2(CO)6]-, Fe2(CO)6(u-TeCH2 CH2Te) or Fe2(CO)6(u-TeCH2CH2CH2Te), respectively. The structures of [BrTe2Fe2(CO)6]-, Fe2(CO)6(u-TeCH2CH2Te) and Fe2( CO)6(u-TeCH2CH2CH2Te) have been performed by single -crystal X- ray diffraction method. Besides, the reaction of NaBiO3 with Mo( CO)6 in MeOH followed by the treatment with [Et4N]Br produces [Et4N]2[BiMo4(CO)12(u3-OMe)3].CH2Cl2. It has been structurally characterized by single-crystal X-ray diffraction method and spectroscopic methods.
