“…We believe that the formation of these clusters is the main reason of the unusual physical properties of these phases. There are many experimental examples which confirm with the considered concept of the universal mechanism of cluster formation [21][22][23][24][25][26][27][28].…”

A universal mechanism of tetrahedral metal cluster formation in crystal with geometrically frustrated pyrochlore sublattices is proposed. It has been shown that the critical irreducible representation τ , which generated the formation of metal clusters in non-centrosymmetrical F43m-phases from high symmetry phases with Fd3m space group, is a one dimensional irreducible representation κ 11 (τ 4 (A 2u )) (in Kovalev notation). The structural theory of metal cluster formation based on group theoretical calculations was published earlier for the case of A-ordered spinel. In this work, the theory is generalized in the case of any high symmetry Fd3m structures that include pyrochlore sublattices. We presented a brief review of such structures and mechanisms of the tetrahedral metal cluster formation. The existence of so called "breathing" pyrochlore sublattices in ordered phases is predicted theoretically. The groups of atoms, between which bond clusters, are found. These groups of atoms define electron correlation effects. Examples of tetrahedral metal cluster formation in ordered spinels, ordered lacunar spinels, ordered Laves phases (MgCu 4 Sn structural type) and ordered pyrochlore are considered. The theoretical results are confirmed by the known experimental facts.

“…Multicomponent sulfide compounds, incl. with AB 2 X 4 , have a complex of physico-chemical, magneto-optical, electro-physical and semiconductor properties [1][2][3][4][5][6][7]. In such semiconductor materials, depending on the composition and state of the magnetic subsystem, it is possible to control electrical and optical parameters.…”

The thermodynamic analysis and the X-ray Phase Analysis (XPA) of the FeS–PbS–In2S3system were carried out. It is shown that along with the triple phases of MIn2S4(M – Fe, Pb) and Pb6In6S21, the Fe1.5Pb5.5In10S22phase also participates in the triangulation of the system. The standard thermodynamic functions for the formation of MIn2S4(M-Fe, Pb), Pb6In6S21and Fe1.5Pb5.5In10S22are estimated. An isothermal section of the FeS–PbS–In2S3system at 298 K is constructed. It is shown that the activation energy of the impurity level located in the band gap of Fe1.5Pb5.5In10S22is equal to 0.19 eV.
