Materials Data on Mo4H8N2O13 by Materials Project

Mo4O13(NH4)2 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of four ammonium molecules and one Mo4O13 ribbon oriented in the (0, 1, 0) direction. In the Mo4O13 ribbon, there are four inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.74–2.50 Å. In the second Mo6+ site, Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.73–2.38 Å. In the third Mo6+ site, Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.73–2.37 Å. In the fourth Mo6+ site, Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.73–2.33 Å. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Mo6+ 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 4-coordinate geometry to four Mo6+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to three Mo6+ atoms. In the fifth O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to two Mo6+ atoms. In the eighth O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom. In the ninth O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to two Mo6+ atoms. In the eleventh O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom. In the twelfth O2- site, O2- is bonded in a 3-coordinate geometry to three Mo6+ atoms. In the thirteenth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Mo6+ atoms.

Materials Data on MoH8(NO2)2 by Materials Project

(NH4)2MoO4 is Iron carbide-derived structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of four ammonium molecules and four MoNH4O4 clusters. In each MoNH4O4 cluster, Mo6+ is bonded in a tetrahedral geometry to four O2- atoms. All Mo–O bond lengths are 1.80 Å. N3- is bonded in a tetrahedral geometry to four H1+ atoms. There is three shorter (1.04 Å) and one longer (1.06 Å) N–H bond length. There are three 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 1.70 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Mo6+ 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 distorted bent 120 degrees geometry to one Mo6+ and one H1+ atom.
