description: C4P2NH17O8 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of two C4P2NH17O8 ribbons oriented in the (1, 0, 0) direction. there are four inequivalent C2- sites. In the first C2- site, C2- is bonded in a trigonal non-coplanar geometry to one C2- and three H1+ atoms. The C–C bond length is 1.53 Å. All C–H bond lengths are 1.10 Å. In the second C2- site, C2- is bonded to one N3- and three H1+ atoms to form corner-sharing CH3N tetrahedra. The C–N bond length is 1.49 Å. There is two shorter (1.09 Å) and one longer (1.10 Å) C–H bond length. In the third C2- site, C2- is bonded in a distorted tetrahedral geometry to one C2-, two P5+, and one O2- atom. Both C–P bond lengths are 1.86 Å. The C–O bond length is 1.44 Å. In the fourth C2- site, C2- is bonded to one N3- and three H1+ atoms to form corner-sharing CH3N tetrahedra. The C–N bond length is 1.49 Å. There is two shorter (1.09 Å) and one longer (1.10 Å) C–H bond length. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to one C2- and three O2- atoms to form distorted corner-sharing PCO3 tetrahedra. There are a spread of P–O bond distances ranging from 1.52–1.61 Å. In the second P5+ site, P5+ is bonded to one C2- and three O2- atoms to form distorted corner-sharing PCO3 tetrahedra. There are a spread of P–O bond distances ranging from 1.52–1.57 Å. N3- is bonded in a distorted tetrahedral geometry to two C2- and two H1+ atoms. There is one shorter (1.04 Å) and one longer (1.06 Å) N–H bond length. There are sixteen inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the fourth 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 fifth H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. 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 N3- and one O2- atom. The H–O bond length is 1.71 Å. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the eleventh H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the twelfth H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the thirteenth H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.06 Å) and one longer (1.46 Å) H–O bond length. In the fourteenth H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.54 Å) H–O bond length. In the fifteenth H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.07 Å) and one longer (1.42 Å) H–O bond length. In the sixteenth H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one P5+ and two H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to one C2- and one H1+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the sixth O2- site, O2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to one P5+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom.
