title: Materials Data on CoPH21N5O7 by Materials Project

description: CoPH17(NO)5(H2O)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of eight water molecules and four CoPH17(NO)5 clusters. In each CoPH17(NO)5 cluster, Co3+ is bonded to five N3- and one O2- atom to form CoN5O octahedra that share a cornercorner with one PO4 tetrahedra. There is one shorter (1.96 Å) and four longer (1.97 Å) Co–N bond length. The Co–O bond length is 1.98 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CoN5O octahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of P–O bond distances ranging from 1.55–1.58 Å. There are five inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to one Co3+ and three H1+ atoms. All N–H bond lengths are 1.03 Å. In the second N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to one Co3+ and three H1+ atoms. There are a spread of N–H bond distances ranging from 1.02–1.04 Å. In the third N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to one Co3+ and three H1+ atoms. There are a spread of N–H bond distances ranging from 1.02–1.04 Å. In the fourth N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to one Co3+ and three H1+ atoms. All N–H bond lengths are 1.03 Å. In the fifth N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to one Co3+ and three H1+ atoms. All N–H bond lengths are 1.03 Å. There are seventeen inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N3- 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 N3- atom. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the eleventh H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.66 Å) H–O bond length. In the twelfth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the thirteenth 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 fourteenth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fifteenth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the sixteenth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the seventeenth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Co3+ and one P5+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one P5+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In the fifth O2- site, O2- is bonded in a water-like geometry to two H1+ atoms.
