“…[10Ϫ12] In addition, organoimido derivatives of polyoxometalates with a remote, active functional group may be exploited to prepare covalently-linked nano-dumbbells, [13,14] polymeric chains [9] and even networks of polyoxometalates in more controllable manners.…”

In the presence of a carbodiimide (DCC) a proton can dramatically speed up the reaction of α‐[Mo8O26]4− with aromatic amines under mild conditions and convenient bench manipulations, which results in the easy synthesis of monofunctionalized organoimido derivatives of [Mo6O19]2− even bearing an electron‐withdrawing group such as bromo or chloro groups.

“…While both areas have been enjoying considerable success, there has been little success in bringing these two types of materials together through covalent bonds. [10,11] Not only will such hybrid materials combine the advantages of organic materials, such as ease in processing and structural fine tuning, with those of inorganic clusters, but the close interaction of organic delocalized p electrons with the cluster d electrons may bring exciting synergistic effects. Such materials with their unique structures are extremely interesting not only to synthetic chemists and materials scientists, but also to theoretical and experimental physicists.…”

The Mo≡N bond is conjugated with the organic segment in the novel molecular organic–inorganic hybrid materials that have been obtained by Pd‐catalyzed coupling of an iodo‐functionalized hexamolybdate anion and an alkyne (see scheme; Ar=4‐methylphenyl,3‐5‐di(tert‐butyl)phenyl). The interaction between the polyoxometalate cluster and the organic conjugated system is particularly apparent from the strong red‐shifted absorption in the UV/Vis spectrum.

Source of materialAsolution of bis(2-hydroxyethyl)selenide (0.17 g, 1.00 mmol) in CH 2 Cl 2 (10 ml) was added to as tirred mixture of [CN(iPr) C 2 Me 2 N(iPr)] (0.36 g, 2.00 mmol) and MoO 2 Cl 2 (0.20 g, 1.00 mmol) in CH 2Cl2 (10 ml) at 0°C. The mixture of the reaction was allowed to come to room temperature and stirred overnight. The resulting suspension was filtered. The filtrate was concentrated to ca. 10 ml in vacuo and diethyl ether (5 ml) was added. The solution was stored overnight at room temperature to yield yellow crystals suitable for X-ray diffraction analysis. Crystals were collected on afilter, washed once with diethyl ether (5 ml) and dried in vacuo. Elemental analysis -found: C, 22.84 %; H, 3.72 %; N, 4.62 %; calculated for C 22H42Mo6N4O19:C,21.27 %; H, 3.41 %; N, 4.51 %. Experimental detailsHydrogen atoms bound to carbon atoms were positioned geometrically and refined using ariding model, with d(C-H) =0.95 Å (CH), 0.98 Å (CH 3 )and U iso (H) =1.2 U eq (CH) or 1.5 U eq (CH 3 ). DiscussionThe hexamolybdate cluster [Mo 6O19] 2-features six terminal oxygen atoms aligned along the unit cell axes, which could make it serve as an octahedrally-directing template. So the hexamolybdate has been extensively studied and employed as build-
