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.
