A new 1D polyoxovanadate containing boric acid [Cu(en)2V10O28][Cu(en)2(H2O)]2 ·2H3BO3·2H2O (1, en = ethylenediamine) has been hydrothermally synthesized and structurally characterized. Compound 1 consists of a polyoxovanadate chain [Cu(en)2V10O284−]n based on the linkage of decavanadate clusters and [Cu(en)2]2+ groups, complex cations [Cu(en)2(H2O)]2+, free H3BO3 and H2O molecules. The polyoxovanadates and boric acid can undergo polycondensation into various B-O-V clusters under hydrothermal conditions, but 1 is the only example of the non-condensation of polyoxovanadate and boric acid. The IR spectrum and the thermal behavior of 1 were also studied.
Key words: Polyoxovanadate, Borate, Hydrothermal Synthesis, Crystal Structure, Boric Acid
