Abstract. The crystal structure of the title compound, Na+.C5H14 -NO7P2-.H20, contains zwitterionic olpadronate anions coordinated to Na ÷ cations. The interactions in the crystal define broad chains which have Na ÷ ions at their core and bis-phosphonate groups near the Na ÷ centres, with the positively charged ends of the zwitterions extending outwards. Strong hydrogen bonds provide both intra- and interchain connectivity.
