The reaction of cyclic trimeric perfluoro-o-phenylenemercury (o-C6F4Hg)3 (1) with the polyhedral [B12H11SCN]2– anion in THF at 20 °C affords the {[(o-C6F4Hg)3](B12H11SCN)}2– (4) and {[(o-C6F4Hg)3]2(B12H11SCN)}2– (5) complexes. Complex 5 was isolated as the tetrabutylammonium salt. X-ray diffraction analysis showed that this complex has a bent-sandwich structure in which the [B12H11SCN]2– anion is located between the planes of two molecules 1 and is coordinated to both these molecules through B—H—Hg bridges and S—Hg bonds. The stability constants of complexes 4 and 5 in THF (20 °C), which were determined from the IR spectroscopic data, are 16 L mol–1 and 992 L2 mol–2, respectively. 相似文献

The Os3(-H)2(CO)7(-C6H4){3-Ph2PCH2P(C6H4)Ph} complex, which was isolated from the products of thermolysis of Os3(CO)10(-dppm) (dppm is Ph2PCH2PPh2) in toluene, was characterized by X-ray diffraction analysis. Protonation of the resulting complex with trifluoroacetic acid afforded the cationic complex [Os3(-H)3(CO)7(-C6H4){3-Ph2PCH2P(C6H4)Ph}]+. 相似文献

The reaction of bromine with exo-nido-ruthenacarborane [Cl(Ph3P)2Ru]-5,6,10-(-H)3-10-H-7,8-C2B9H8 (1) led to the replacement of the chlorine atom by the bromine atom in the octahedral environment of the ruthenium atom rather than to the substitution in the carborane cage. The structure of [Br(Ph3P)2Ru]-5,6,10-(-H)3-10-H-7,8-C2B9H8 was established by NMR and IR spectroscopy and X-ray diffraction analysis. 相似文献

NMR spectroscopy has been used to study the thermal rearrangement of siliconeopentyl esters of phosphorus acids Me3SiCH2OP(O)R2 (I, R=CF3CH2O, PhO, t-BuCH2O, Bu). It has been established that in all cases the products of the rearrangement are the respective silyl esters Me2EtSiOP(O)R2 (II). The thermal rearrangement of (Me3SiCH2O)2P(O)OR (III, R'=Ph, t-BuCH2, Me3SiCH2) is similar. It has been shown that electronic and steric attributes of the substituents R and R on the phosphorus atom are practically without effect on the extent of the thermal rearrangement. The presence of acidic additives, and initiators and inhibitors of radical reactions did not significantly influence the course of the rearrangement. It was concluded that this rearrangement apparently takes place as a result of heterolysis of the C-OP bond and simultaneous nucleophilic attack on the silicon atom by the phosphoryl part of the molecule.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 5, pp. 1155–1158, May, 1991. 相似文献

The first double-decker sandwich complex of a sandwich was synthesized and fully characterized. The complex was prepared by the reaction of cyclic trimeric perfluoro-o-phenylene-mercury (o-C6F4Hg)3 (1) with ferrocene in an ethereal solution at 20 °C and has the composition {[(o-C6F4Hg)3]2(Cp2Fe)} (2). The ferrocene sandwich in 2 is located between the planes of two mercury-containing macrocycles and is coordinated to each of them through donation of the -electrons of the 5-Cp ligands to vacant orbitals of the mercury atoms of the adjacent molecule 1. It was concluded that all carbon atoms of the 5-Cp rings in complex 2 are involved in the bonding to the macrocycles. Complexation with 1 leads to considerable shifts of the (C-H) and (C-H) bands of ferrocene in the IR spectrum to high frequencies. The structure of complex 2 was determined by X-ray diffraction.__________Published in Russian in Izvestiya Akademii Nauk. Seriya Khimicheskaya, No. 12, pp. 2754–2756, December, 2004. 相似文献
