“…Strikingly, the neighboring 2D networks are stabilized via hydrogen bonding interactions between μ 1 ‐Htpim and Ot atoms of [SiMo 12 O 40 ] 2– linking Cu [typical hydrogen bondings: N10–H10B ··· O40 2.843(6) Å], ultimately generating a 3D supramolecular structure (Figure ). Noticeably, in compound 1 , Keggin‐type polyoxomolybdates coordinating directly to metal ion and extending 3D network by hydrogen bonds simultaneously is rare …”

Two new 1D helical coordination polymers based on polyoxometalate were synthesized by self-assembly of Keggin-type POMs and copper salts in the presence of triangular N-heterocyclic derivatives or long-chain N-containing carboxylate ligand, that are, (H 3 O)[{Cu(H 2 tpim) 2 }{SiMo 12 O 40 }]·0.5H 2 O [Htpim = 2,4,5-tri(4-pyridyl)-imidazole] (1) and [Cu 2 (Hcpp) 3 (cpp)(H 2 O)][PMo 12 O 40 ]·2H 2 O [Hcpp = 1-(4-cyanobenzyl)-3-2-yl)pyrazole] (2). Their structures were determined by single-crystal X-ray diffraction and further characterized by elemental analyses and TG analyses. Compounds 1 and 2

Three 1D/2D HgII coordination polymers (CPs), namely {[Hg3(L)2Cl6](H2O)}n (1), [Hg(L)Br2]n (2), and [Hg(L)I2]n (3) were prepared by assembly of 3,4‐bis(3‐pyridyl)‐5‐(4‐pyridyl)‐1,2,4‐triazole (L) with different inorganic HgII salts (i.e. HgCl2, HgBr2 or HgI2). Single‐crystal X‐ray diffraction analysis reveals two types of bimetallic subunits [(Hg)2C6N4] and [(Hg)2C12N6] in CP 1, which are further extended to a 2D coordination network. Both of CPs 2 and 3 show 1D zigzag arrays bridged by L ligands. Notably, the L ligands take the (η4, μ4) coordination fashion in 1 but (η2, μ2) binding mode in 2 and 3. The structural differences of CPs 1–3 indicate that the L ligand can adjust its coordination fashions to meet the requirements of HgII centers, relying on the presence of distinct halide anions. In addition, 1 can be applied to fabricate an electrochemical biosensor for the detection of penicillin.

“…A promising synthetic strategy to improve POM catalyst system is the combination of POM with metal–organic coordination complexes to construct crystalline inorganic–organic hybrid compounds‐based POMs with high‐dimensional supramolecular networks . In comparison with the traditional POMs, inorganic–organic hybrid of POMs can merge the merits of both components, and the combination may lead to desirable catalytic activity .…”

An inorganic–organic hybrid based on lanthanide clusters and Keggin type polyoxometalates (POMs) (Na[Nd (pydc‐OH)(H2O)4]3}[SiW12O40]) was used the first time as trinuclear catalyst for one pot synthesis of pyrazolo[4́́,3́:5,6]pyrido[2,3‐d]pyrimidine‐diones, via two different four and five‐component reactions involving hydrazine hydrate, ethyl acetoacetate, aryl aldehydes, and 6‐amino‐1,3‐dimethyl uracil or barbituric acid with ammonium acetate as alternative materials in green condition. To evaluate potential application of the as‐made hybrid in adsorption and separation processes, nitrogen adsorption was performed at 77 K through simulation study. The hybrid catalyst was further characterized via powder X‐ray diffraction (PXRD) at room temperature which indicated the good phase purity of the catalyst. The results show that the catalytic activity of the hybrid catalyst has increased relative to each parent component due to the special interaction between Keggin anions and pydc‐OH ligands.
