Ethylenediammonium gallic vanadium hydrogen sulfate monohydrate

Abstract

The title compound, tetrakis(ethylenediammonium) gallium trivanadium octakis(hydrogen sulfate) tetrahydroxide tetrahydrate, (C2H10N2)4[GaV3(SO4)8(OH)4]·4H2O, was obtained hydrothermally from an aqueous solution of VOSO4, Ga2O3, ethylenediamine, glycol and sulfuric acid. The structure features a one‐dimensional chain built from MO6 octahedra (site symmetry , M = V or Ga) and bridging OH and SO4 groups.

A Slow Leak Synthetic Route to Organically Templated Gallium Sulfates

“…The assignment of a hydroxyl group in the [Ga(OH)(SO 4 ) 2 ] n 2 n − chain backbone in 2 is consistent with the well-known structures of tancoite ,,, and related analogues. Inclusion of this hydrogen results in a reasonable bond valence for the bridging oxide of 2.09.…”

“…See Figure b. This compound is isostructural to both [H 3 N(CH 2 ) 2 NH 3 ][V III (OH)(SO 4 ) 2 ]·H 2 O and (C 2 H 10 N 2 ) 4 [GaV 3 (SO 4 ) 8 (OH) 4 ]·4H 2 O …”

“…Despite widespread successes in the creation of organically templated gallium phosphates and fluorophosphates during the past 15 years, − the chemistry of templated gallium sulfates is essentially unexplored. To the best of our knowledge, the only reported example of a templated metal sulfate that contains gallium is the disordered, vanadium/gallium compound, [C 2 H 10 N 2 ] 4 [GaV 3 (SO 4 ) 8 (OH) 4 ]·4H 2 O . The syntheses and structures of the first four organically templated gallium sulfates are reported here.…”
