catena-Poly[2,2′,2′′-nitrilotris(ethanaminium) [tri-μ-oxido-tris[dioxidovanadate(V)]] monohydrate]

Abstract

The title compound, {(C6H21N4)[V3O9]·H2O}n, crystallizes as a salt with [trenH3]3+ cations [tren is tris­(2-amino­eth­yl)amine], and one-dimensional anionic {[VVO3]−}n (metavanadate) chains along the c-axis direction. Three crystallographically distinct VV sites and one occluded water mol­ecule are present for every [trenH3]3+ cation in the unit cell. The {[VVO3]−}n chains are composed of vertex-sharing [VO4] tetra­hedra and have a repeat unit of six tetra­hedra. Each tetra­hedron in the chain contains two terminal and two μ2-bridging oxide ligands. The [trenH3]3+ cations, {[VVO3]−}n anions and occluded water mol­ecules participate in an extensive three-dimensonal hydrogen-bonding network. The three terminal ammonium sites of the [trenH3]3+ cations each form strong N—H⋯O hydrogen bonds to terminal oxide ligands on the {[VVO3]−}n chain. Each occluded water mol­ecule also donates two O—H⋯O hydrogen bonds to the terminal oxide ligands.
