Reactions of [H2Os3(CO)10] with the substituted diynes R−C2−C2−R' (1, R = Ph, R' CH2NHPh; 2, CH2NHCH2Ph; 3, CH2NHPh) afford clusters [HOs3(CO)10(L)] (L {μ-η1:η2-PhCH2C(H)C−C(H)C−NPh} (4), {μ-η1:η2-PhCH2C(H)C−C(H)C−NCH2Ph} (5), and {μ-η1:η1-CH3CCC−C(H)C(H)−NPh} (6), which have been characterized by single-crystal X-ray diffraction analyses as well various spectroscopic methods. In 4−6, starting 1−3 rearranged to form pyrrolyl rings bridge two osmium atoms in η1:η2- (4, 5) or η1:η1- (6)...
Reactions between unsaturated [H(2)Os(3)(CO)(9)(PR(3))] clusters (PR(3)= PPh(3), P(4-CF(3)-C(6)H(4))(3), PEt(3)) and 2,4-hexadiyne-1,6-diol have been studied. It was found that the diyne ligand easily reacts with all these complexes to give [HOs(3)(CO)8(PR3)-[mu3, eta1:eta3:eta1)-(CH(3)-C-C=CH-CH=C-O)]] (V, VI VII, respectively) containing "Os3C3" pentagonal pyramid cluster framework. This structural pattern is formed through cyclization, dissociation of a CO eventual coordination cyclized...
The enthalpy of the oxotransfer reaction [Bu4N]2[WO2(mnt)2] (where mnt2– is maleonitriledithiolate) with PPh3 in an inert atmosphere acetonitrile solution was determined by calorimetry. obtained value (−93 ± 5) kJ mol–1 differs from carried out us earlier under aerobic conditions (16 9) mol–1. results indicate participation atmospheric oxygen catalytic process. DFT calculations structures [MOx(LL)2]2– M = Mo or W, x 1 2, and LL dithiolene ligand) were out. thermodynamic potential values for...
Thermodynamic data on the properties of water-based electrolyte systems are very valuable for fundamental physical chemistry and industrial applications. The missing both dilution dissolution enthalpies ternary CsCl-MgCl2-H2O mixed system were investigated by means calorimetry method. was performed at 298 K set solutions from diluted to concentrated constant ratio Cs+/Mg2+=1.8. relative partial molar enthalpies, ideal, total, excess ones calculated. By calorimetry, standard formation,...
This article presents new possibilities of using thin films lanthanide stearates as sorbent materials. Modification the Q-sense device resonator with monolayers by Langmuir-Schaeffer method made it possible to study process insulin protein adsorption on surface thin-film sorbents. The resulting were also characterized compression isotherms, chemical analysis, scanning electron microscopy, and mass spectrometry. transition stearic acid salt was recorded IR spectroscopy. Using LDI MS method,...
Abstract In this article the possibility of obtaining Langmuir-Blodgett films on basis octadecylamine monolayers containing nanoparticles hexacyanoferrates various metals was shown. A comparison made between different methods for these particles. Nanoparticles were produced using sodium hexametaphosphate as a stabilizer, their average size determined by laser diffraction. The isotherms compression studied subphase nanoparticles. Optimal conditions transfer to solid substrate chosen according...
