Abstract

The iron carbonyl tellurido cluster (Ph₄P)₂[Fe₄Te2(CO)₁₄] (1) has been synthesized at 80°C in moderate yield by heating a mixture of Fe₃(CO)₁₂, Na₂Te₂, and Ph₄PBr in a 2:1:6 molar ratio in a sealed Pyrex tube containing 0.4 ml of methanol. Another cluster, Cs[HFe₃Te(CO)₉] (2) has been prepared similarly by allowing Fe₃(CO)₁₂ to react with Cs₂Te₃ (4: 1 molar ratio) in 0.2 ml of H₂O at 130°C. Compound 1 crystallizes in the monoclinic space group C2/c (No. 15) with a = 23.324(3) Å, b = 11.793(2) Å, c = 23.499(5) Å, β = 102.02(1)°, V = 6322(2) Å³, Z = 4. A central 'Fe₂(μ₃-Te)₂(CO)₆' butterfly unit remains connected to two Fe(CO)₄ fragments through the tellurium atoms in the anion of 1. Compound 2 crystallizes in the orthorhombic space group Pbca (No. 61) with a = 9.672(2) Å, b = 15.816(4) Å, c = 21.430(5) Å, V = 3278(2) Å³, Z = 8. In the anion of this compound, a Te^2- ligand caps a triiron triangle to form an approximate tetrahedron, with a hydride ligand bridging one of the Fe-Fe bonds. Both compounds have been characterized by solid state and solution infrared spectroscopy and ¹²⁵Te NMR spectroscopy.
