X-ray emission spectroscopic data on atomic states of 4d-elements in the cluster compounds of Mo-Tc-Ru series

Method for comparative study on chemical bonds in 4d transition element series based on comparison of chemical effects in X-ray emission K-spectra and their interpretation within the frames of isolated atom-ion model is proposed. Variations in character of distribution of Mo-Tc-Ru series elements on Kα1,2-Kβ1,3 doublets chemical shift diagrams as well as on diagrams of Q5s and Q4d relative partial changes are identified. General regularity of increased density of 4d states impact on metal atom in all cases of M-M-interactions realization is demonstrated on Q5s-Q4d diagrams. 18 refs.; 7 figs.; 4 tabs
