Graphical Abstract
Die Gegenwart bestimmter Donormoleküle entscheidet, ob Bariumhypersilanide als Koordinationsverbindungen (siehe Bild) oder als Ionenpaare vorliegen: In aromatischen Lösungsmitteln dissoziieren die Verbindungen unter Bildung diskreter Ionen. Die Silanide sind bedeutsam als effektive Initiatoren für Polymerisationen und wichtige Modellverbindungen in der metallorganischen Chemie der schweren Erdalkalimetalle.

All crystals were mounted on the diffractometer as described elsewhere.[18] The data were collected using a Bruker SMART system, complete with three-circle goniometer and CCD detector as described earlier.[8] The crystal structure of 1 was solved using direct methods whereas Patterson methods were used to solve 2 and 3. All structures were refined by full-matrix least-squares refinement on F2.[19] An absorption correction was applied for all structures.[20] All non-hydrogen atoms in 1 and 3 were refined anisotropically. Significant disorder was detected for 2, resulting in the isotropic refinement of some of non-hydrogen atoms and the use of bond-distance restraints.[19] CCDC 206684–206686 contain the supplementary crystallographic data for this paper.
