MoPNO7 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of two MoPNO7 ribbons oriented in the (0, 0, 1) direction. Mo6+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Mo–O bond distances ranging from 1.71–2.17 Å. P5+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.47 Å) and two longer (1.50 Å) P–O bond length. N3+ is bonded in a water-like geometry to two O2- atoms. There is one shorter (1.19 Å) and one longer (1.42 Å) N–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one N3+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one N3+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mo6+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Mo6+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a single-bond geometry to one P5+ atom.
(MoOPO4)4N2O2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four ammonia molecules, four water molecules, and one MoOPO4 framework. In the MoOPO4 framework, there are two inequivalent Mo+4.50+ sites. In the first Mo+4.50+ site, Mo+4.50+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with two equivalent MoO6 octahedra, corners with four PO4 tetrahedra, and an edgeedge with one MoO6 octahedra. The corner-sharing octahedra tilt angles range from 45–48°. There are a spread of Mo–O bond distances ranging from 1.94–2.06 Å. In the second Mo+4.50+ site, Mo+4.50+ is bonded to six O2- atoms to form distorted MoO6 octahedra that share corners with two equivalent MoO6 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 45–48°. There are a spread of Mo–O bond distances ranging from 1.69–2.21 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four MoO6 octahedra. The corner-sharing octahedra tilt angles range from 40–46°. There is two shorter (1.53 Å) and two longer (1.57 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four MoO6 octahedra. The corner-sharing octahedra tilt angles range from 27–55°. There are a spread of P–O bond distances ranging from 1.51–1.60 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to three Mo+4.50+ atoms. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mo+4.50+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo+4.50+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mo+4.50+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one Mo+4.50+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one Mo+4.50+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to one Mo+4.50+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mo+4.50+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to one Mo+4.50+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to one Mo+4.50+ and one P5+ atom.
