Description
Summary:Molybdenum polyoxometalate buckyballs (NH₄)₄₂[MO ₇₂ VI MO ₆₀ V O₃₇₂(ClCH₂COO)₃₀(H₂O)₇₂] · 250H₂O · 15ClCH₂COONa (Mo132Cl) were synthesized; some of their properties were studied, namely, purity, spectral and crystallographic parameters, buckyball aggregation in solution, and interaction with water-soluble nonionic polymers (poly(vinyl alcohol) and poly(vinylpyrrolidone)). The newly synthesized polyoxometalate was shown to have a lower stability than its analogue containing acetate instead of chloroacetate groups, both having similar thermal destruction pathways. At the first heating steps, water is eliminated from Mo132Cl. Thermal destruction at higher temperature produces chloroacetamide, chloroacetonitrile, and other compounds.
