Реферат:	eng: Raman spectra were acquired from the synthetic cubic K6Fe25S26Cl phase (55.3wt% Fe) and ten natural djerfisherites K-6(Fe,Cu,Ni)(25)S26Cl with various contents of Fe (from 15.5 to 22.6 atoms per formula unit (apfu)) and Ni+Cu+Co (from 1.4 to 9.0 apfu). The natural samples came from rocks of the Udachnaya, Obnazhennaya and Vtorogodnitsa kimberlite pipes and high-grade contact marbles near Kochumdek River (Siberian craton, Russia). Diagnostic features of both synthetic and natural djerfisherite Raman spectra can be summarized as follows: the presence of two strong bands at 264-273 and 321-344cm(-1) and from two to five medium/weak bands in the region from 90 to 190cm(-1). Raman spectra of Fe-rich ((Ni+Cu+Co)<2.4 apfu) djerfisherite have up to nine bands, whereas the number of Raman bands in spectra of djerfisherite with high impurity concentration ((Ni+Cu+Co)=8.7-9 apfu) reduces to four. The Raman spectra of djerfisherite enriched in impurities ((Ni+Cu+Co)=5-9 apfu) are also characterized by broadening and asymmetry of bands in comparison with Ni+Cu+Co-poor djerfisherite. Experimental Raman spectra of synthetic and natural djerfisherites show good agreement with theoretical spectra calculated using lattice-dynamical software. The group of bands in the range 90-190cm(-1) is associated with the S-Fe-S bending vibrations in FeS4 tetrahedra and FeS6 octahedra. The band group in the range of 260-350cm(-1) is due to the Fe-S stretching vibrations in both polyhedra. Copyright (c) 2017 John Wiley & Sons, Ltd.
