Zusammenfassung: | The Ga84R20 4- [R = N(SiMe3)2] species, which represents the largest metalloid cluster entity structurally characterized so far, has been electronically and topologically modified: Via changing the redox potential of the reaction solution, crystals different from those containing the Ga84R20 4- anion can be isolated, featuring similar Ga84R20 3- entities. An accurate crystal structure analysis via synchrotron radiation is presented, which might be the first step toward an understanding of the metallic conductivity and superconductivity of the Ga84R20 4- cluster compound, physical properties which are singular in the field of metalloid clusters so far. |
