Crystal structure of the deuterated hepta­hydrate of potassium phosphate, K(3)PO(4)·7D(2)O

Deuterated potassium orthophosphate hepta­hydrate, K(3)PO(4)·7D(2)O, crystallizes in the Sohnke space group P2(1), and its absolute structure was determined from 2017 Friedel pairs [Flack parameter 0.004 (16)].

Descripción
Sumario:Deuterated potassium orthophosphate hepta­hydrate, K(3)PO(4)·7D(2)O, crystallizes in the Sohnke space group P2(1), and its absolute structure was determined from 2017 Friedel pairs [Flack parameter 0.004 (16)]. Each of the three crystallographically unique K(+) cations is surrounded by six water mol­ecules and one oxygen atom from the orthophosphate group, using a threshold for K—O bonds of 3.10 Å. The highly irregular coordination polyhedra are linked by corner- and edge-sharing into a three-dimensional network that is consolidated by an intricate network of O—D⋯O hydrogen bonds of medium strength.
