Abstract
The compound Na7[Na⊂{(MoV 2O4)3(μ2-OH)3H(PhPO3)4}2] · 2N2H4 · 26 H2O (formulation with respect to the aggregate in the crystal) has been synthesized and characterized by single-crystal X-ray structure analysis (which alone does not allow the determination of the formula), UV/Vis/NIR/IR, 31P{1H}, 1H and 23Na NMR spectroscopy as well as magnetic susceptibility measurements. The compound is formed under similar conditions as (NH2Me2)6[H2⊂(MoV 2O4)6O4(μ2-C)H)12(MoVIO3)4].Correspondingly, both cluster frame works are built up by the same {(MoV 2O4)3(μ2-OH)3}3+ units.Keywords
