Na3P3(H5O7)2H2O crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of two water molecules and one Na3P3(H5O7)2 sheet oriented in the (0, 1, 0) direction. In the Na3P3(H5O7)2 sheet, there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with three PO4 tetrahedra and edges with three NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.32–2.52 Å. In the second Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with three PO4 tetrahedra and edges with three NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.41–2.50 Å. In the third Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with five PO4 tetrahedra and edges with four NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.38–2.44 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four NaO6 octahedra and corners with two PO4 tetrahedra.

In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are fourteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the fourth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Na1+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one Na1+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Na1+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to two Na1+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to two Na1+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted water-like geometry to one Na1+ and two H1+ atoms.
