Abstract

Abstract: A novel intercluster compound, [( n ‐C4 H9 )4 P]3 [H3 V10 O28 ] (IL01 ‐V10 ), constructed from the tetrabutylphosphonium cation and decavanadate, has been synthesized and unequivocally characterized by elemental analysis, FTIR spectroscopy, mass spectrometry, X‐ray crystallography, and solution 1 H, 13 C, 31 P{ 1 H}, and 51 V NMR spectroscopy. Compound IL01 ‐V10 was formed by ionic interaction between the phosphonium cation and the decavanadate anion. Cryospray high‐resolution mass spectrometry revealed the [H3 V10 O28 ] 3– cluster remains intact in solution. Three further phosphonium polyoxovanadates were synthesized and characterized by the same techniques as used for IL01 ‐V10 . Abstract : Four new phosphonium decavanadate hybrid materials have been synthesized and characterized by various spectroscopic methods. Single‐crystal X‐ray diffraction of IL01 ‐V10 revealed that the [H3 V10 O28 ] 6– anionic unit remains intact and that three phosphonium ionic liquid are electrostatically coupled to one decavanadate unit.
