New synthetic approach to the preparation of palladium(II)-based heterobimetallic complexes was proposed. The complexes were prepared in high yields (85-95%) in single-crystalline form and structurally characterized by physicochemical methods, including X-ray structural analysis. All the complexes are built based on the structural motif [Pd(-OOCR)4M] (R = Me, tBu; M = Cu(II), Zn(II), Ni(II), Co(II), Mn(II), Ce(IV), Nd(III), Sm(III), Eu(III), Tm(III), Yb(III)). Reduction of the heterobimetallic complexes can produce new mixed-metal nanomaterials

The complexation in the system Rh(III) – H<sub>2</sub>SO<sub>4</sub> – H<sub>2</sub>O at the room temperature in the dilute sulfuric acid has been studied by 103Rh and 17O NMR. The most stable species in solutions are [Rh<sub>2</sub>(μ-SO<sub>4</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>8</sub>] <sup>2+</sup> and [Rh<sub>2</sub>(μ-OH)(μ-SO<sub>4</sub>)(H<sub>2</sub>O)<sub>8</sub>] <sup>3+</sup>; we have established that the solid «rhodium sulfates” are amorphous glassy phases with variable composition

Data of experimental and theoretical study (DFT method) of electron-rich metal phenanthrocyanines – new class of tetraazachromophore complexes of delements Pt2+, Pd2+, Rh3+, Cr3+, Co2+, Ni2+, Zn2+ and Cd2+ was presented. On basis of experimental data on electron absorption spectra (EAS) and quantum chemical calculations of EAS of model anion-radical 1,10-phenanthroline and electron-rich 1,10-phenanthroline complexes suggest of long-wave bands in EAS of metal phenanthrocyanines was made. Some general regularities of new metal phenanthrocyanines formation in C(sp2 )H-C(sp2 )H-coupling reactions of coordinated 1,10-phenanthrolines concerned with metal promotion and elementary electron and proton transfer processes in initialization stage of C(sp2 )H-C(sp2 )H-coupling was analysed

The article is aimed at solving the problem of directed synthesis of substances with given properties and creation of new functional materials on their base. The concrete fundamental task is chemical design of new multifunctional (TWC) catalysts that ensure simultaneous conversion of carbon monoxide, carbon hydrоcarbons and nitrogen oxides. The main idea of chemical TWC catalyst construction is realization of segregate interaction of NO and CO with the surface substance y-AI2O3+ZrxCe1-xO2
