V2H6O11(NH3)2NHH2O crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four ammonia molecules, eight ammonia molecules, four water molecules, and four V2H6O11 clusters. In each V2H6O11 cluster, there are two inequivalent V5+ sites. In the first V5+ site, V5+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of V–O bond distances ranging from 1.64–2.02 Å. In the second V5+ site, V5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.63–2.22 Å. There are six 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 1.01 Å. In the second H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.63 Å) H–O bond length. In the third 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 fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the sixth 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 eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one V5+ and one H1+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and one O2- atom. The O–O bond length is 1.37 Å. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and one O2- atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one V5+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one V5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two V5+ and one H1+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two V5+ and one H1+ atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one V5+ atom. In the ninth O2- site, O2- is bonded in a distorted water-like geometry to three H1+ atoms. In the tenth O2- site, O2- is bonded in a single-bond geometry to one H1+ and one O2- atom. The O–O bond length is 1.42 Å. In the eleventh O2- site, O2- is bonded in a distorted water-like geometry to one V5+ and one O2- atom.
