Abstract:	The crystal structure of trisodium monophosphate hemihydrate was determined. The space group is $C2 c$ and a unit cell contains eight formula units. The unit cell dimensions of $Na_{3} PO_{4} · 12 H_{2} O$ are a = 9.631(3), b = 5.416(2), c = 16.938(8) Å, β = 102.60(5)°. The final R value is 0.027 for a set of 1430 independent reflections. This atomic arrangement is mainly a three-dimensional network of distorted NaO₆ octahedra. The hydrogen bonding scheme is given.
