The structures of the hypophosphites KH2PO2 ( potassium hypophosphite), RbH2PO2 ( rubidium hypophosphite) and CsH2PO2 ( caesium hypophosphite) have been determined by single-crystal X-ray diffraction. The structures consist of layers of alkali cations and hypophosphite anions, with the latter bridging four cations within the same layer. The Rb and Cs hypophosphites are isomorphous.
