Two Anderson-type polyoxometalate-based hybrids constructed with different bis(pyrazine)-bis(amide) ligands: Efficient adsorption dyes and electrocatalytic activities
By regulating the spacer lengths of the ligands, two Anderson-type polyoxometalate-based metal-pyrazinamide hybrids, namely, {HCu(L1)[AlMo6(OH)(6)O-18])center dot 4H(2)O (1), {HCu(L2)(H2O)(2)[AlMo6(OH)(6)O-18])center dot 4H(2)O (2) (L1 = N,N’-bis(2-pyrazinecarboxamide)-1,2-ethane, L2 = N,N’-bis(2-pyrazinecarboxamide)-1,4-butane) were prepared through hydrothermal methods, and characterized by powder X-ray diffraction, IR spectra, gravimetric analyses and single-crystal X-ray diffraction analysis. Crystal analysis demonstrates that 1 is a 2D network composed of the mu(2)-bridging L1 ligands and the bidentate bridging Anderson anions [AlMo6(OH)(6)O-18](3)(AlMo6). Complex 2 is a 3D supramolecular architecture consists of the AlMo6 anions and the metal-organic chains [Cu(L2)](n)(2n+) via hydrogen bonds. The result demonstrates that both 1 and 2 display adsorption capacities toward methylene blue (MB) and gentian violet (GV) in aqueous solutions and possess reusability. In addition, the electrocatalytic reduction performances of the title complexes were explored. (C) 2020 Elsevier Ltd. All rights reserved.
