Abstract
Two novel organic–inorganic hybrid supramolecular compounds based on organoammonium cations (OACs) and polyoxomolybdates (POMs), namely, [BDMLPX]3[Mo8O26]2[H3O]2·H2O (1) [BDMLPX = di(1,2-dimethylimidazolium) p-xylene dichloride and [BIIT][HBIIT][ClMo12O40] (2) [BIIT = 1,3-bis(imidazole-3-iumyl)-2,4,6-trimethyl benzene], have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, infrared spectroscopy, and thermal gravimetric analysis. Compound 1 contains the β-[Mo8O26]4−cluster and 2 has the classical Keggin-type discrete [ClMo12O40]− anion.
