Abstract
The new complex K[Al(mal)(2)(H2O)(2)] . 2H(2)O [H(2)mal = CH2(CO2H)(2)] has been synthesized and its crystal structure determined by X-ray crystallography. An investigation of metal speciation in aqueous solution (analytical concentration around 50 mmol dm(-3)) by using Al-27, H-1 and C-13 NMR spectroscopies revealed that, in solutions at physiological pH (7.5), the bis(malonate) complex evolves to the tris(malonate), [Al(mal)(3)](3-), without precipitation of aluminium hydroxide.File in questo prodotto:
