Polyoxomolybdate–Surfactant Layered Crystals Derived from Long-tailed Alkylamine and Ionic Liquid

Polyoxomolybdate inorganic–organic hybrid crystals were synthesized by using long-tailed primary amine and ionic-liquid surfactants. Dodecylamine and 1-dodecyl-3-methylimidazolium bromide were employed for the syntheses. Both hybrid crystals contained a β-type octamolybdate (Mo8) anion and showed alternate stacking of Mo8 monolayers and interdigitated surfactant bilayers. The arrangement of Mo8 layers in the inorganic monolayers was different between the hybrid crystals because of the difference in the structures of the surfactant hydrophilic head.
