description: H2MoO4H2O crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of sixteen water molecules and two H2MoO4 sheets oriented in the (0, 1, 0) direction. In each H2MoO4 sheet, 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 1.74–2.32 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 1.74–2.32 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 1.74–2.31 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 1.74–2.32 Å. There are eight inequivalent H1+ sites. In the first 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 second 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 third 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 fourth 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 fifth 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 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 single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are sixteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to one Mo6+ and two H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to one Mo6+ and two H1+ atoms. In the third O2- site, O2- is bonded in a water-like geometry to one Mo6+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a water-like geometry to one Mo6+ and two H1+ 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 single-bond geometry to one Mo6+ atom. 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 bent 150 degrees geometry to two Mo6+ atoms. In the tenth O2- site, O2- is bonded in a bent 150 degrees geometry to two Mo6+ atoms. In the eleventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Mo6+ atoms. In the twelfth O2- site, O2- is bonded in a distorted linear geometry to two Mo6+ atoms. In the thirteenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Mo6+ atoms. In the fourteenth O2- site, O2- is bonded in a bent 150 degrees geometry to two Mo6+ atoms. In the fifteenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Mo6+ atoms. In the sixteenth O2- site, O2- is bonded in a bent 150 degrees geometry to two Mo6+ atoms.
