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.

“…In this case, the influence of the alkali cations seems to be critical during the synthesis and self-assembly of the nanoclusters. The critical influence of cations on the nanocluster synthesis has been demonstrated both experimentally [18][19][20][21][22][23] and theoretically. 24 One of the mostdeveloped members of these host-guest materials is the uranylperoxide cluster.…”

Quantum chemical calculations were performed to explore the structural and electronic properties of the two polyoxoaurates, [Au(III)4As(V)4O20](8-) (Au4As4) and [Au(III)4Se(IV)4O16](4-) (Au4Se4), known to date, and a number of hypothetical polyoxoaurate derivatives comprising heteroatoms different from arsenic and selenium (namely, Si, Ge and P). In addition, the interactions of [Au(III)4X4Om](n-) (X = As, Se) with alkali-metal cations (Li(+), Na(+), K(+) and Rb(+)) are also analysed. The studies suggest that the geometry structure, electronic properties and nucleophilicity of oxygen atoms of these polyoxoaurates are tuned by the size or electronegativity of the heteroatoms (Si, Ge, P, As and Se). Then, the geometry of [Au(III)4X4Om](n-) (X = As and Se) coordinating with alkali cations from Li(+) to Rb(+) and the complexation energy between [Au(III)4X4Om](n-) and alkali cations were compared. The results show that the stability and electronic structure of heteropolyoxoaurates depend on the entrapped cations. On the basis of the complexation energy, it can be concluded that the ion-pairing effect in arsenate-capped oxoaurate is stronger than that in selenite-capped oxoaurate. These heteropolyoxoaurates are expected to play a role in aqueous behaviour, self-assembly characteristics of polyoxoaurates, ion recognition, selectivity studies and may exhibit potential guest-switchable redox properties.
