A new 3D extended structural compound,(dpdo)_2H_2{[Cu(2,2’-bipy)_2]_2(P_2W_(18)O_(62))}·5H_2O 1(dpdo = 4,4’-bipyridine-N,N’-dioxide; 2,2’-bipy = 2,2’-bipyridine),has been hydrothermally synthesized and characterized by elemental analyses,IR,TG analyses,cyclic voltammetry,and single-crystal X-ray diffraction.Compound 1 is built up of[P_2W_(18)O_(62)]~(6-) cluster as the structural motif covalently linked by[Cu(2,2’-bipy)_2]~(2+) coordination complexes to yield the 1D chains,which are further in close contact forming a 3D supramolecular framework via aromaticπ-πstacking interactions and extensive hydrogen-bonding interactions among polyoxoanions,coordinated 2,2’-bipy organic ligands,free dpdo organic molecules and lattice water molecules.
A new 3D extended structural compound, (dpdo) _2H_2 {[Cu (2,2’-bipy) _2] _2 (P_2W_ (18) O_62)} 5H_2O 1 (dpdo = 4,4’-bipyridine-N , N’-dioxide; 2,2’-bipy = 2,2’-bipyridine), has been hydrothermally synthesized and characterized by elemental analyzes, IR, TG analyzes, cyclic voltammetry, and single-crystal X-ray diffraction. is built up of [P_2W_ (18) O_ (62)] ~ (6-) cluster as the structural motif covalently linked by [Cu (2,2’-bipy) _2] chains, which are further in close contact forming a 3D supramolecular framework via aromatic π-π stacking interactions and extensive hydrogen-bonding interactions among polyoxoanions, coordinated 2,2’-bipy organic ligands, free dpdo organic molecules and lattice water molecules.
