Abstract

The new complex K[Al(mal)2(H2O)2]·2H2O [H2mal = CH2(CO2H)2] was synthesized and its crystal structure detd. by x-ray crystallog. A study of metal speciation in aq. soln. (anal. concn. around 50 mmol dm-3) by using 27Al, 1H and 13C NMR spectroscopies revealed that, in solns. at physiol. pH (7.5), the bis(malonate) complex evolves to the tris(malonate), [Al(mal)3]3-, without pptn. of aluminum hydroxide.
