    Description / Table of Contents: Zusammenfassung Kaliumtetraphenylimidodiphosphinat, [K][Ph 2P(O)NP(O)Ph 2], reagiert mit 18-Krone-6-ether unter Ausbildung des mohydydratisierten Komplexes [K(18-Krone-6)][Ph 2P(O)-NP(O)Ph 2]. Die Verbindung zeigt eine Kalium-Sauerstoff-Wechselwirkung under Formierung eines anorganischen (Kohlenstoff-freien) Chelat-Ringes. Dies ist im Gegensatz zum Schwefel-Analogen, das keine Kation-Anion-Wechselwirkung zeigt.
    Notes: Summary Potassium tetraphenylimidodiphosphinate, [K][Ph 2P(O)NP(O)Ph 2], reacts with 18-crown-6 ether to give the monohydrated complex [K(18-crown-6][Ph 2P(O)NP(O)Ph 2]·H2O. The compound shows an interaction potassium-oxygen, forming an inorganic (carbon free) chelate ring and it is different to the sulphur homolog which has no interaction cation-anion.
