Four novel organic-inorganic hybrid arsenic-vanadate complexes, [Cu(phen)][(As-V O-4) (V-V O-3(7))(H2O)] (1), [ Cu(en)2] 2[As8V14O42(H2O)] center dot 2.5H(2)O (2), [ M(1,10-phen)(3)](2) [As8V14O42(H2O)(0.)5] center dot 0.5H(2)O (M Mn, 3, Cd, 4) ( 1,10- phen 1,10- phenanthroline) have been hydrothermally synthesized for the first time and characterized by elemental analyses, XPS spectra, EPR spectra, IR spectra, TG analyses and single crystal X-ray diffraction. The structure of compound 1 consists of arsenic vanadate ribbons coordinated by the [Cu(phen)](2+) complex, while compounds 2 to 4 possess a spherical [(As8V14O42)-V-III-O-IV](4-) cage with H2O molecules encapsulated. The unexpected preparation 1 and the synthesis of compounds 2 to 4 on the basis of same polyoxoanion structures show that the pH value of the reaction plays a crucial role in controlling the basic architectures.
