description: NbC4H8O13NH4H2O crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four ammonium molecules, four water molecules, and four NbC4H8O13 clusters. In each NbC4H8O13 cluster, Nb5+ is bonded in a distorted pentagonal bipyramidal geometry to seven O2- atoms. There are a spread of Nb–O bond distances ranging from 1.76–2.34 Å. There are four inequivalent C3+ sites. In the first C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.23 Å) and one longer (1.32 Å) C–O bond length. In the second C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.24 Å) and one longer (1.29 Å) C–O bond length. In the third C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.24 Å) and one longer (1.30 Å) C–O bond length. In the fourth C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.24 Å) and one longer (1.30 Å) C–O bond length. 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 0.98 Å. In the third 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 fourth H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.61 Å) H–O bond length. In the fifth 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 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 1.01 Å. In the eighth 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 (1.64 Å) H–O bond length. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three H1+ atoms. In the second O2- site, O2- is bonded in a single-bond geometry to one C3+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one C3+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Nb5+ and one C3+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one C3+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Nb5+ and one C3+ atom. In the seventh O2- site, O2- is bonded in a single-bond geometry to one C3+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Nb5+ and one C3+ 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 distorted water-like geometry to one Nb5+ and two H1+ atoms. In the eleventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Nb5+ and one C3+ atom. In the twelfth O2- site, O2- is bonded in a distorted single-bond geometry to one Nb5+ atom. In the thirteenth O2- site, O2- is bonded in a distorted water-like geometry to one Nb5+ and two H1+ atoms.
