Abstract

Li2CuP6(HO5)4(CN3H6)2(H2O)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional and consists of two guanidinium molecules, two water molecules, and one Li2CuP6(HO5)4 framework. In the Li2CuP6(HO5)4 framework, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four PO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.90–2.06 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 1.99–2.40 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, a cornercorner with one LiO4 tetrahedra, and corners with two PO4 tetrahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent LiO4 tetrahedra and corners with two PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.64 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CuO6 octahedra, a cornercorner with one LiO4 tetrahedra, and corners with two PO4 tetrahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of P–O bond distances ranging from 1.50–1.63 Å. There are two inequivalent H1+ sites. In the first 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 second 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 ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees 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 bent 120 degrees geometry to two P5+ atoms. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Li1+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two P5+ atoms. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Li1+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a water-like geometry to one Cu2+ and two H1+ atoms.
