Hybrid single crystals consisting of an organic surfactant and an inorganic moiety are promising functional materials. Layered crystals composed from alternate inorganic and surfactant layers are obtained by the template effect of long alkyl chain moiety. The composition, crystal packing, and molecular arrangement of the hybrid single crystals are controllable by changing the inorganic constituent and the surfactant molecular structure. The types of hybrid surfactant single crystals are twofold: (i) crystals consisting of discrete inorganic cation coordinated by ligands having amphiphilic moiety; and (ii) crystals comprising a surfactant cation and a discrete inorganic anion including polyoxometalate (POM) oxide clusters. The POM-surfactant hybrid single crystals are rather rare, and therefore promising as unprecedented functional materials. Their structural variation and functional properties are discussed.

“…To construct well-ordered polyoxometalate-ionic liquid hybrids, utilizing structure-directing species such as surfactant molecules [ 23 , 24 , 25 ] is advantageous. Polyoxometalate anions have been organized by surfactant cations to form inorganic-organic hybrids [ 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ] and single crystals [ 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 ]. These polyoxometalate-surfactant hybrids allow flexible selection of the ionic components, which leads to precise engineering of the structure and function.…”

A polyoxomolybdate inorganic-organic hybrid crystal was synthesized with deprotonatable ionic-liquid surfactant. 1-dodecylimidazolium cation was employed for its synthesis. The hybrid crystal contained δ-type octamolybdate (Mo8) isomer, and possessed alternate stacking of Mo8 monolayers and interdigitated surfactant bilayers. The crystal structure was compared with polyoxomolybdate hybrid crystals comprising 1-dodecyl-3-methylimidazolium surfactant, which preferred β-type Mo8 isomer. The less bulky hydrophilic moiety of the 1-dodecylimidazolium interacted with the δ-Mo8 anion by N–H···O hydrogen bonds, which presumably induced the formation of the δ-Mo8 anion. Anhydrous conductivity of the hybrid crystal was estimated to be 5.5 × 10−6 S·cm−1 at 443 K by alternating current (AC) impedance spectroscopy.

Keggin-type polyoxotungstate hybrid layered crystals are successfully synthesized in a single phase by using a heterocyclic surfactant. Heteropolyoxotungstate anions of [XW 12 O 40 ] n-(XW 12 , X = P, Si; n = 3, 4) are hybridized with the dodecylpyridazinium (C 12 pda) cation. Single-crystal X-ray diffraction analyses reveal that all of the countercations of XW 12 are replaced by C 12 pda cations. The layered structures consist of XW 12 inorganic layers and C 12 pda organic layers, stacked al- [a]
