Popis: Hexakis[bis(2-aminoethoxy)methylsilylethyl]benzene and hexakis[bis(N,N-dimethyl-2-aminoethoxy)methylsilylethyl]benzene C6[(NR2CH2CH2O)2SiMeCH2CH2]6 (4, R = H; 5, R = Me) were prepared from hexakis(methyldichlorosilylethyl)benzene C6(Cl2MeSiCH2CH2)6 and 2-aminoethanol or N,N-dimethyl-2-aminoethanol, respectively. Compounds 4 and 5 react with anhydrous cobalt (ii) chloride to give poorly soluble dodecachloro{hexakis[bis(2-aminoethoxy)methylsilylethyl]benzene}hexacobalt and dodecachloro{hexakis[bis(N,N-dimethyl-2-aminoethoxy)methylsilylethyl]benzene}hexacobalt {Co6[(NR2CH2CH2O)2SiMeCH2CH2]6C6}Cl12 (R = H or Me), respectively. Polyfunctional amine 4 reacts with dicobalt octacarbonyl to produce hexakis[bis(2-aminoethoxy)methylsilylethyl]benzenedicobalt(ii) tetrakis(tetracarbonylcobaltate) {Co2[(NH2CH2CH2O)2SiMeCH2CH2]6C6}[Co(CO)4]4. N,N-Dimethyl-substituted polyfunctional amine 5 is lowly reactive in the reaction with Co2(CO)8, whereas the simplest model of this compound, viz., bis(N,N-dimethyl-2-aminoethoxy)dimethylsilane (NMe2CH2CH2O)2SiMe2, slowly reacts with Co2(CO)8 to give tris[bis(N,N-dimethyl-2-aminoethoxy)dimethylsilane]cobalt(ii) bis(tetracarbonylcobaltate) {Co[(NMe2CH2CH2O)2SiMe2]3}[Co(CO)4]2. Thermal decomposition and transformations of the resulting complexes under the action of oxygen and water were studied.
