Abstract
Crystals of anhydrous K, Rb, and Cs hypophosphites have been obtained. The structures of these compounds were determined by X-ray diffraction analysis. The structure in general is a packing of layers of metal cations and hypophosphite anions coordinated to them. In all compounds, the hypophosphite anion performs the function of a bridge between four cations in a layer. Each oxygen atom is linked to two cations. The compounds RbH2PO2 and CsH2PO2 are isostructural.
