Bei der Bildung metalloider Ga‐Cluster führen Phosphoniumbetaine zu einem Ga12‐Gerüst mit ungewöhnlichen Bindungsverhältnissen

During the Formation of Metalloid Gallium Clusters Phosphoniumbetaines lead to a Ga₁₂ Network with unusual Bonding Properties The reaction of a 3:1 mixture of a phosphanid and a phosphorus ylide with a metastable solution of GaBr leads to a neutral, metalloid Ga₁₂‐cluster compound. This for the frist time observed metalloid cluster with positivly polarized phosphonium ligandes and a negativly polarized Ga₁₂‐core will be disussed by quantum chemical calculations with regard to the amount of the charge transfer.
