Materials Data on AsH18N3O7 by Materials Project
NH4AsN2H14O7 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four ammonium molecules and four AsN2H14O7 clusters. In each AsN2H14O7 cluster, As5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.72 Å) and two longer (1.73 Å) As–O bond length. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a tetrahedral geometry to four H1+ atoms. There are a spread of N–H bond distances ranging from 1.04–1.06 Å. In the second N3- site, N3- is bonded in a tetrahedral geometry to four H1+ atoms. There is two shorter (1.05 Å) and two longer (1.06 Å) N–H bond length. There are fourteen 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- and one O2- atom. The H–O bond length is 1.73 Å. 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 distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.63 Å) H–O bond length. In the sixth 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 seventh 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 (1.68 Å) H–O bond length. 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- and one O2- atom. The H–O bond length is 1.73 Å. 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 single-bond geometry to one N3- atom. In the twelfth 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 thirteenth H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.70 Å) H–O bond length. In the fourteenth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one As5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one As5+ and one H1+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one As5+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to one As5+ and three H1+ atoms. In the fifth O2- site, O2- is bonded in a water-like geometry to two H1+ atoms. In the sixth O2- site, O2- is bonded in a water-like geometry to two H1+ atoms. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to three H1+ atoms.
