The
controllable synthesis of two vanadium-containing polyoxoniobate-based
three-dimensional organic–inorganic hybrid compounds, [Co(pn)2]4[HPNb10VIV2O40(VIVO)4]·17H2O (1) and [Co(pn)2]5[PNb12O40(VIVO)6](OH)7·15H2O (2), where pn = 1,2-diaminopropane, is realized
by changing the hydrothermal temperature or adding N-(aminoethyl)piperazine as an additive. Both compounds 1 and 2 are structurally characterized by single-crystal/powder
X-ray diffraction and IR and X-ray photoelectron spectroscopy. Compound 1 features a new divanadium-substituted Keggin polyoxoniobate
capped by four vanadyl groups, and the polyanion in 2 exhibits the highest coordination number (10-connected) in polyoxoniobate
chemistry. Moreover, the photocatalytic activities of 1 and 2 for hydrogen evolution are preliminarily assessed.
