N2 - Anionic iron(0) tetracarbonyl with terminal phenyltellurolate ligand PhTe−, [PhTeFe(CO)4]−, has been synthesized and characterized. The title compound was obtained by addition of (PhTe)2 to [PPN][HFe(CO)4] THF solution dropwise. [PPN][PhTeFe(CO)4] crystallizes in the monoclinic space group C c, with a = 16.119(4) Å, b = 13.141(3) Å, c = 19.880(8) Å, β = 93.04(3)°, V = 4205(2) Å3, and Z = 4. The [PhTeFe(CO)4]− anion is a trigonal‐bipyramidal complex in which the phenyltellurolate ligand occupies an axial position with Fe‐Te bond length 2.630(5) Å and the Fe‐Te‐C(Ph) angle is 103.4(5)°. The neutral iron(0)‐telluroether compound, (PhTeMe)Fe(CO)4, was prepared by alkylation of the [PhTeFe(CO)4]−. Protonation of [PhTeFe(CO)4]−and reaction of H2Fe(CO)4 and PhTe)2 ultimately lead to formation of the known dimer Fe2(μ‐TePh)2(CO)6 and H2.
