Na4CuP6(H4O11)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with five PO4 tetrahedra and an edgeedge with one NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.37–2.57 Å. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.41–2.71 Å. Cu2+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with four PO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 1.97–2.38 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 a cornercorner with one CuO6 octahedra, corners with two equivalent NaO6 octahedra, and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 31–59°. There are a spread of P–O bond distances ranging from 1.49–1.64 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one NaO6 octahedra, a cornercorner with one CuO6 octahedra, and corners with two PO4 tetrahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of P–O bond distances ranging from 1.49–1.63 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent NaO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 40–61°. There are a spread of P–O bond distances ranging from 1.50–1.64 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.71 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.76 Å) H–O bond length. 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 0.98 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, one P5+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Cu2+ and one P5+ atom. 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 bent 120 degrees geometry to one Na1+ and two P5+ atoms. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Cu2+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two Na1+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to three Na1+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, one P5+, and one H1+ atom. In the tenth O2- site, O2- is bonded in a distorted water-like geometry to one Cu2+ and two H1+ atoms. In the eleventh O2- site, O2- is bonded in a distorted water-like geometry to two Na1+ and two H1+ atoms.
