Synthesis and structures of distibene (RSb:SbR) and bridging stibinidene (RSb) iron complexes Academic Article uri icon

abstract

  • The reaction of (Me3Si)2CHSbCl2(4) with Na2[Fe(CO)4] affords a mixture of the distibene complex, [Fe(η2- {(Me3Si)2CH}2Sb2)(CO)4] (5), and the “closed” stibinidene complex, [Fe2{μ-SbCH(SiMe3)2}(CO)8] (6). The structures of 4, 5, and 6 were determined by single-crystal X-ray diffraction methods. Compound 4 crystallizes in the monoclinic space group P21/n with a = 7.021 (3) Å, b= 17.129 (10) Å, c = 12.490 (4) Å, and β = 99.64 (3)°. Compound 5 crystallizes in the monoclinic space group P21/n with a = 19.958 (4) Å, b = 6.635 (1) Å, c = 24.408 (6) Å, and β = 103.51 (2)°. Compound 6 crystallizes in the triclinic space group PĪ with a = 7.065 (5) Å, b = 9.179 (2) Å, c = 19.814 (7) Å, α = 86.86 (3)°, β = 85.23 (5)°, γ = 70.04 (4)°. The reaction of 5 with Fe2(CO)9 produces 6, an unstable compound, 14, believed to be the “open” isomer of 6, and an iron-antimony cluster, [{Fe(CO)3}3}(Me3Si)2CHSb}2], (15). © 1985, American Chemical Society.
