Syntheses and Crystal Structures of [μ‐(Me3SiCH2Sb)5–Sb1,Sb3–{W(CO)5}2] and [{(Me3Si)2CHSb}3Fe(CO)4] – Two Cyclic Complexes with Antimony Ligands cyclo‐(Me3SiCH2Sb)5 reacts with [(THF)W(CO)5] (THF = tetrahydrofuran) to form cyclo‐[μ‐(Me3SiCH2Sb)5–Sb1,Sb3–{W(CO)5}2] ( 1 ). The heterocycle cyclo‐ [{(Me3Si)2CHSb}3Fe(CO)4] ( 2 ) is formed by an insertion reaction of cyclo‐[(Me3Si)2CHSb]3 and [Fe2(CO)9]. The crystal structures of 1 and 2 are reported. 相似文献

The iron complexes [(Et2Sb)4Fe4(CO)14] ( 1 ), [(nPr2Sb)4Fe3(CO)10] ( 2 ), [{(Me3SiCH2)2Sb}4Fe2(CO)6] ( 3 ), and [2‐(Me2NCH2)C6H4SbFe2(CO)8] ( 4 ) were prepared by reactions of distibanes with Fe2(CO)9. Compounds 1 – 4 were characterized by X‐ray diffraction, 1H NMR and IR spectroscopy as well as mass spectrometry; complex 1 was additionally characterized by density functional calculations. 相似文献

Syntheses and Structures of η1‐Phosphaallyl, η1‐Arsaallyl, and η1‐Stibaallyl Iron Complexes [(η5‐C5Me5)(CO)2Fe–E(SiMe3)C(OSiMe3)=CPh2] (E = P, As, Sb) The reaction of equimolar amounts of [(η5‐C5Me5)(CO)2Fe–E(SiMe3)2] ( 1 a : E = P; 1 b : As; 1 c : Sb) and diphenylketene afforded the η1‐phosphaallyl‐, η1‐arsaallyl‐, and η1‐stibaallyl complexes [(η5‐C5Me5)(CO)2Fe–E(SiMe3)C(OSiMe3)=CPh2] ( 2 a : E = P; 2 b : As; 2 c : Sb). The molecular structures of 2 b and 2 c were elucidated by single crystal X‐ray analyses. 相似文献

Novel Syntheses of Me2SbX (X = Cl, I) and Crystal Structures of Me2SbI and [(Me3Si)2CH]2SbCl The crystal structures of Me2SbI (Me = CH3) and [(Me3Si)2CH]2SbCl have been determined by X‐ray methods. Both molecules are pyramidal. The Me2SbI molecules are associated to chains through short intermolecular Sb…I distances (366,7(1) pm) with linear I–Sb…I units (171,87(4)°) and bent Sb–I…Sb bridges (116,83(3)°). 相似文献

Synthesis, Structure, and Reactivity of the Ferrioarsaalkene [(η5‐C5Me5)(CO)2FeAs=C(Ph)NMe2] Reaction of equimolar amounts of the carbenium iodide [Me2N(Ph)CSMe]I and LiAs(SiMe3)2 · 1.5 THF afforded the thermolabile arsaalkene Me3SiAs = C(Ph)NMe2 ( 1 ), which in situ was converted into the black crystalline ferrioarsaalkene [(η5‐C5Me5)(CO)2FeAs=C(Ph)NMe2)] ( 2 ) by treatment with [(η5‐C5Me5)(CO)2FeCl]. Compound 2 was protonated by ethereal HBF4 to yield [(η5‐C5Me5)(CO)2FeAs(H)C(Ph)NMe2]BF4 ( 3 ) and methylated by CF3SO3Me to give [(η5‐C5Me5)(CO)2FeAs(Me)C(Ph)NMe2]‐ SO3CF3 ( 4 ). [(η5‐C5Me5)(CO)2FeAs[M(CO)n]C(Ph)NMe2] ( 5 : [M(CO)n] = [Fe(CO)4]; 6 : [Cr(CO)5]) were isolated from the reaction of 2 with [Fe2(CO)9] or [{(Z)‐cyclooctene}Cr(CO)5], respectively. Compounds 2 – 6 were characterized by means of elemental analyses and spectroscopy (IR, 1H, 13C{1H}‐NMR). The molecular structure of 2 was determined by X‐ray diffraction analysis. 相似文献

On the Reactivity of (η5-C5Me5)(CO)2FeP(SiMe3)2 Toward P-Chloromethylene phosphanes The reaction of (η5-C5Me5)(CO)2FeP(SiMe3)2 ( 2 ) with three equivalents of Cl? P?C(SiMe3)2 ( 3a ) afforded the 3-methanediyl-1,3,5,6-tetraphosphabicyclo[3.1.0]hex-2-ene (η5-C5Me5)(CO)2Fe? ( 6a ). In contrast, 2 reacts with two equivalents of Cl? P?C(Ph)SiMe3 ( 3b ) to give the thermolabile (η5-C5Me5) · (CO)2Fe? P[P?C(Ph)SiMe3]2 ( 4b ) which decomposed during the reaction with further 3b. 4 b was also obtained from (η5-C5Me5)(CO)2Fe? P(SiMe3)? P?C(SiMe3)2 ( 1a ) and two equivalents of 3b . 相似文献

Synthesis and Crystal Structure of (C5H5)Mo(CO)3(AuPPh3) and [(C5H5)Mo(CO)2(AuPPh3)4]PF6 CpMo(CO)3(AuPPh3) is obtained by the reaction of Li[CpMo(CO)3] with Ph3PAuCl at ?95°C in CH2Cl2. It crystallizes in the monoclinic space group C2/c with a = 2625.1(7), b = 883.2(1), c = 2328.4(7) pm, β = 116.39(1)° und Z = 8. In the complex the AuPPh3 group is coordinated to the CpMo(CO)3 fragment with a Au? Mo bond of 271,0 pm. The Mo atom thus achieves a square pyramidal coordination with the center of the Cp ring in apical position. CpMo(CO)3(AuPPh3) reacts under uv irradiation with an excess of Ph3PAuN3 to afford the cluster cation [CpMo(CO)2(AuPPh3)4]+. It crystallizes as [CpMo(CO)2(AuPPh3)4]PF6 · 2 CH2Cl2 in the orthorhombic space group P212121 with a = 1553.9(1), b = 1793.8(2), c = 2809.8(7) pm und Z = 4. The five metal atoms form a trigonal bipyramidal cluster skeleton with the Mo atom in equatorial position. The Mo? Au distances range from 275.5 to 280.8 pm, and the Au? Au distances are between 281.2 and 285.6 pm. 相似文献
