Homogeneous hydrolysis of aluminum by decomposition of urea in solution was achieved because the urea coordinates to the Al3+ in solution, forming [Al(H2O)5(urea)]3+ and to a lesser extent [Al(H2O)4(urea)2]3+. Upon hydrolysis more hydrolyzed monomeric species, [Al(H2O)5(OH)]2+, [Al(H2O)4(OH)2]+, [Al(H2O)4(urea)(OH)]2+, and [Al(H2O)3(urea)(OH)2]+, were formed, followed by trimeric species and the Al13 Keggin complex [AlO4Al12(OH)24(H2O)12]7+. The 27Al NMR spectra indicated the formation of other complexes in addition to the Al13 at the end of the hydrolysis reaction.

30 citations in Scopus
26 citations in Web of Science®
Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
