A new 1D compound [(H2bpe)Mo4O13] (1) (bpe=trans-1,2-Di-(4-pyridyl)-ethylen) was hydrothermally synthesized and characterized. Compound 1 comprises 3D supramolecular network constructed from 1D [Mo4O13]2-anion chains and protonated bpe layers via hydrogen bonds and π-π stacking interactions. The crystal data are the following: C12H12Mo4N2O13, Monoclinic, space group P21/n, a=0.968 64 (13) nm, b=1.349 68 (18) nm, c=1.514 9(2) nm, β=99.766(2)°, Z=4. The inorganic chain built up from only molybdenum oxide building blocks is interesting. The luminescent property of 1 was studied.
An isopolytungstate(NH4)6Na4[H2W12O42]·14H2O(1) has been synthesized in an aqueous solution and characterized by elemental analysis,IR spectroscopy,TG analysis,X-ray powder diffraction(XRD) and single-crystal X-ray diffraction.The result indicates a degradation from nitrilotriacetic acid(NTA) to NH3.The electrochemical analysis and thermal stability of 1 were also studied.The crystal data are as follows:H54N6Na4O56W12(Mr = 3332.65),orthorhombic,Pbca,a = 14.1497(15),b = 15.9414(16),c = 22.931(2) ,Z = 4,V = 5172.4(9) 3,Dc = 4.280 Mg/m3,μ = 26.729 mm-1,F(000) = 5904,the final R = 0.0809 and wR = 0.2104 for 4565(Rint = 0.1351) independent reflections.The β-[H2W12O42]10-clusters are linked through {Na2(OH2)3} groups into a 2D layer and are further connected into a 3D framework via hydrogen bonding interactions.
