Abstract
The mono-hydrate phase as well as the water-free RbD2PO4 (DRDP) is obtained by crystal growth from fully deuterated aqueous solution. Its crystal stru cture was determined by combined neutron and X-ray single crystal diffracti on. It consists of double layers of PO4 tetrahedra with D2O planes in betwe en. The PO4 groups are linked by fully ordered deuterium bonds O-D-O. RbD2P O4. D2O dehydrates below 329(5)K and undergoes a phase transition to RbD2PO 4(DRDP).
