Effects of protonation in decavanadates: crystal structure of tetrakis(n-hexylammonium) dihydrogendecavanadate(V)

Abstract

The crystal structure of a new dihydrogendecavanadate(V) of n-hexylammonium has been determined by means of X-ray diffraction data. Empirical bond length/bond number calculations have located the protonation sites in two triply-linked oxygen atoms which reinforce theoretical results of relative basicities of the oxygen sites in decavanadate anions. The crystal structure is stabilised by electrostatic forces and an extensive network of hydrogen contacts among anions and cations. The dihydrogendecavanadate(V) anions are located on the (001) plane and are joined via hydrogen bonding, d(O ⋯ O)= 2.63 and 2.64 Å, giving evidence of strong O ⋯ O interactions. Infrared spectroscopy and thermoanalytical methods have been applied in order to confirm structural properties.
