d, h-μ-Benzylalkoxophosphonato-e-μ-alkoxo-f-μ-oxo-bis[trichloroantimony(V)] Compounds The binuclear antimony(V) complexes Cl3Sb(O)[R3(R1O)PO2](OR2)SbCl3 1 – 6 with R1 = R2 = CH3, C2H5 and R3 = C6H5CH2, (CH3)3C6H2CH2 in solution slowly exchanges the R2 groups between the oxygen atoms of the Sb2O2 ring. The SbOPOSb ringsystem makes rapid pseudorotation. The isomeres are detected by nmr spectroscopy. 1 (R1 = R2 = CH3) crystallizes in the orthorhombic space group Pnma with a = 1247.0, b = 1324.1, c = 1207.9 pm and Z = 4. 2 (R1 = CH3, R2 = C2H5) and 5 (R1 = R2 = CH3, R3 = (CH3)3 · C6H2CH2) crystallizes triclinic in the space group P-1 with a = 984.1, b = 1026.7, c = 1079.9 pm, α = 87.93, β = 75.70, γ = 87.62° and Z = 2 and a = 1164.6, b = 1296.9, c = 1712.9 pm, α = 109.9, β = 96.3, γ = 100.2° and Z = 4 resp., with two crystallographically independent molecules in the asymmetric unit. 相似文献

d,h-μ-Methanesulfonato-, d,h-μ-Methanesulfinato-e-μ-hydroxo/alcoxo-f-μ-oxo-bis-[trichloroantimonies(V)] The title compounds can be prepared by reaction of dimeric tetrachloroantimony(V) methanesulfinate or methanesulfonate resp. or by reaction of methane sulfinic acid or sulfonic acid resp. with addition compounds of antimony(V) chloride and water/alcohol. The vibrational spectra are assigned and discussed. 相似文献

dh-μ-Carboxilato-e-μ-hydroxo-f-μ-oxo-bis[trichloroantimonies(V)] Structure and Spectroscopic Investigations The title compounds can be prepared by reaction of SbCl5 · H2O and RCOOH (R ? CF3, CCl3, CHCl2, CH2Cl, CH3, CH3CH2, (CH3)2CH, H) or by reaction of H5O2+SbCl6? and RCO2SbCl4 in good yields. 1H-NMR investigations proove that there is a rapid exchange between the components in the reaction mixture. The vibrational spectra are discussed in view of the CO2 vibrations and hydrogen bonding. The crystal and molecular structure of dh-μ-Trichloroacetato-e-μ-hydroxo-f-μ-oxo-bis[trichloroantimony(V)] is determined by X-ray analysis. 相似文献

μd,h-μ-Carboxilato-e-μ-methoxo-f-μ-oxo-bis[trichloroantimony(V)]. Preparation and Spectra The preparation of the unknown d,h-μ-carboxilato-e-μ-methoxo-f-μ-oxo-bis[trichloroantimony(V)] compounds is described (CF3COO ? 2 , CH3CH2COO ? 4 ). The vibrational spectra of 2 and 4 were assigned and compared with those of the corresponding hydroxo compounds 1 and 3 . The mass spectra of 1—4 are measured and the fragmentation pathes are proposed. The formulae of some fragments of 1 with m/e values greater than the molecular weight were determined by high resolution. 相似文献
