Abstract

The new clusters Fe2 M(CO)10(µ3-S)(µ3-Te), I (M=W) and 2 (M=Mo) have been isolated from the room temperature reaction of Fe2(CO)6(µ-STe) andM(CO)5(THF) (M=W, Mo), respectively. Compounds1 and2 have been characterized by IR, 125 Te NMR spectroscopy, and elemental analysis. The structure of compound1 has been established by X-ray crystallography. It belongs to the triclinic space groupP \(\bar 1\) witha=6.844(2) Å,b=9.397(2) Å,c=13.681(10) Å, α=81.64(2)°,β=81360r,γ=812(2)°,V=861.2(3) Å3,Z=2,D e =2.835 g cm−3. Full-matrix least-squares refinement of1 converged to R=0.043, andR w .=0.115. The structure consists of a Fe2 WSTe square pyramid and the W atom occupies the apical site of the square pyramid.
