A stable tri-μ-chloro binuclear complex of iron(II) can be formed with the tripod ligand 1,1,1-tris((diethylphosphino)methyl)ethane (etriphos). The X-ray structure determination of the compound [Fe2Cl3(etriphos)2]BPh 4·CH2Cl2 (triclinic P1, a = 18.835 (6) A?, b = 17.433 (6) A?, c = 10.977 (4) A?, α = 106.65 (5)°, β = 92.52 (5)°, γ = 107.24 (5)°) has shown that the geometry is confacial bioctahedral. With use of the Summerville and Hoffmann recent theoretical approach to M2L9 complexes, a comparison of the geometrical and electronic features of this complex with those of the analogous [Fe2H3(triphos)2]PF 6·1.5CH2Cl2 (triphos = 1,1,1-tris((diphenylphosphino)methyl)ethane) is performed. A particularly good agreement is observed between the elongation of the bioctahedron experimentally observed in this tri-μ-chloro complex and that predicted by MO calculations for the [Fe2Cl3(CO)6]+ model.
