A novel inorganic-organic hybrid compound [Cu(dpq)2]4[As8V14O42(H2O)]·2H2O(dpq=dipyrido[3,2-d:2’,3’-f]quinoxaline) was synthesized under the hydrothermal condition and its structure was characterized via single-crystal X-ray diffraction,elemental analysis,IR and XPS spectra.The title compound crystallizes in a monoclinic crystal system,space group P21/c with crystal parameters a=1.8973(3) nm,b=2.5816(2) nm,c=2.8941(2) nm,β=106.61(2)°,V=13.5846(12) nm3,Z=4,R1=0.0674,wR2=0.1750.It possesses a spherical [As8V14O42(H2O)]4-cluster anion,four [CuI(dpq)2]+ counter cations and two lattice water molecules.The cationic complexes form ca.0.8 nm×0.8 nm stellate channels along the c axis through strong π…π stacking interactions due to the multiple aryls in the dpq ligands.The polyoxoanions are embedded in the channels through extensive C—H…O short contact interactions.
A novel inorganic-organic hybrid compound [Cu (dpq) 2] 4 [As8V14O42 (H2O)] .2H2O (dpq = dipyrido [3,2- d: 2 ’, 3’-f] quinoxaline) was synthesized under the hydrothermal condition and its structure was characterized via single-crystal X-ray diffraction, elemental analysis, IR and XPS spectra. The title compound crystallizes in a monoclinic crystal system, space group P21 / c with crystal parameters a = 1.8973 (3) nm, b = 2.5816 (2) nm, c = 2.8941 (2) nm, β = 106.61 (2) °, V = 13.5846 (12) nm3, Z = 4, R1 = 0.0674, wR2 = 0.1750.It possesses a spherical [As8V14O42 (H2O )] 4-cluster anion, four [CuI (dpq) 2] + counter cations and two lattice water molecules. The cationic complexes form ca.0.8 nm × 0.8 nm stellate channels along the c axis through strong π ... π stacking interactions due to the multiple aryls in the dpq ligands.
