- 中文摘要: Anionic iron(0) tetracarbonyl with terminal phenyltellurolate ligand PhTe/sup -/, [ PhTeFe(CO)/sub 4/ ]/sup -/, has been synthesized and characterized. The title compound was obtained by addition of (PhTe)/sub 2/ to [ PPN] [ HFe(CO)/sub 4/ ] THF solution dropwise. [ PPN ] [ PhTeFe(CO)/sub 4/ ] crystallizes in the monoclinic space group C c, with a=16.119(4).ANG., b=13.141(3).ANG., c=19.880(8).ANG., .beta.=93.04(3).degree., V=4205(2).ANG./sup 3/, and Z=4. The [ PhTeFe(CO)/sub 4/ ] /sup -/ anion is a trigonal-bipyramidal complex in which the phenyltellurolate ligand occupies an axial position with Fe-Te bond length 2.630(5).ANG. and the Fe-Te-C(Ph) angle is 103.4(5).degree.. The neutral iron(0)-telluroether compound,(PhTeMe)Fe(CO)/sub 4/, was prepared by alkylation of the [ PhTeFe(CO)/sub 4/ ] /sup -/. Protonation of [ PhTeFe(CO)/sub 4/ ] /sup -/ and reaction of H/sub 2/ Fe(CO)/sub 4/ and (PhTe)/sub 2/ ultimately lead to formation of the known dimer Fe/sub 2/(.mu.-TePh)/sub 2/(CO) /sub 6/ and H/sub 2/.
