A copper-containing polyoxovanadate nanocluster, [(C2H5)4N]4
[V8Cu2O24]∙2H2O (1), was synthesized through reaction between the
Cu(NO3)2∙3H2O and [(C2H5)4N]4VO3 in the molar ratio 1 : 4. Nanocluster
1 was characterized by IR, elemental analysis, XRD, SEM, TEM, and
X-ray crystallography. The catalytic activity of 1 for the azide–alkyne
cycloaddition of different terminal alkynes and organic azides
generated in situ from sodium azide and different organic halides
was tested. The protocol could afford the corresponding products in
good to excellent yield at very low catalyst loadings (3.4 Mol%) under
the optimized reaction conditions.
