| Abstract: | The quaternary systems M-Re-S-Br (M = Na, K, Rb, Cs) have been investigated in the domains of composition which are expected to lead to the formation of Re6 octahedral cluster based compounds. A number of compounds have been obtained. They include the ternaries Re6S4+xBr10−2x (integer x = 0–4) among them crystal data are reported for Re6S4Br10 and Re6S5Br8. Various quaternaries are also presented. Most of them are built from the ¦Re6S4+nBr10−n¦n− anionic units (n = 1–4) stacked in various compounds and solid solutions, the structure of which strongly depends on the number and size of counter cations. |
