In these compounds the cluster core composition varies monotonically, the geometry of the cluster and the rhenium coordination polyhedron are retained unchanged, while the symmetry of the cluster changes. The vibrational spectra (Raman and IR) were recorded and analyzed for compounds with all possible S\/Br ratios in the cluster core. The group vibrations of clusters were attributed with the use of DFT calculations of vibrational spectra. It is shown that the set of main characteristic bands is retained in both ionic and polymeric compounds regardless of the composition and the symmetry of the cluster core while the observed vibration frequencies of these bands depend on the S\/Br ratio in the cluster core. In particular, the group Re\u2013S stretching vibrations (A1g(S8) and T2g(S8) modes) shifted to higher frequencies with the increase in the number of Br atoms in the cluster. The difference in the connectivity in polymeric compounds leads to an increase in the number of bands in the spectra and to the disappearance of the A1g(Br) modes.<\/jats:p>","DOI":"10.3390\/sym15091791","type":"journal-article","created":{"date-parts":[[2023,9,19]],"date-time":"2023-09-19T23:11:52Z","timestamp":1695165112000},"page":"1791","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Systematic Study of Vibrational Spectra of Octahedral Rhenium Clusters {Re6S8-xBrx}Bry (x = 0, 1, 2, 3, 4) with Mixed Sulfur\/Bromine Inner Ligands"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5848-7750","authenticated-orcid":false,"given":"Alexandra Yu.","family":"Ledneva","sequence":"first","affiliation":[{"name":"Nikolaev Institute of Inorganic Chemistry, Siberian Branch of Russian Academy of Sciences, 630090 Novosibirsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariia N.","family":"Ivanova","sequence":"additional","affiliation":[{"name":"Nikolaev Institute of Inorganic Chemistry, Siberian Branch of Russian Academy of Sciences, 630090 Novosibirsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pavel A.","family":"Poltarak","sequence":"additional","affiliation":[{"name":"Nikolaev Institute of Inorganic Chemistry, Siberian Branch of Russian Academy of Sciences, 630090 Novosibirsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Spartak S.","family":"Yarovoy","sequence":"additional","affiliation":[{"name":"Nikolaev Institute of Inorganic Chemistry, Siberian Branch of Russian Academy of Sciences, 630090 Novosibirsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Boris A.","family":"Kolesov","sequence":"additional","affiliation":[{"name":"Nikolaev Institute of Inorganic Chemistry, Siberian Branch of Russian Academy of Sciences, 630090 Novosibirsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vladimir E.","family":"Fedorov","sequence":"additional","affiliation":[{"name":"Nikolaev Institute of Inorganic Chemistry, Siberian Branch of Russian Academy of Sciences, 630090 Novosibirsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7531-6291","authenticated-orcid":false,"given":"Nikolay G.","family":"Naumov","sequence":"additional","affiliation":[{"name":"Nikolaev Institute of Inorganic Chemistry, Siberian Branch of Russian Academy of Sciences, 630090 Novosibirsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"213","DOI":"10.1016\/S0010-8545(03)00083-3","article-title":"Hexanuclear and higher nuclearity clusters of the Groups 4\u20137 metals with stabilizing \u03c0-donor ligands","volume":"243","author":"Gray","year":"2003","journal-title":"Coord.
