Cra. Catlow et al., AB-INITIO AND MOLECULAR-MECHANICS STUDIES OF ALUMINOSILICATE FRAGMENTS, AND THE ORIGIN OF LOWENSTEINS RULE, Chemical communications, (11), 1996, pp. 1311-1312
We present results of the energies of formation and hydration of small
clusters and rings containing Si and Al; the results provide a ration
alisation of Lowenstein's rule in terms of the energetics of species c
ontaining Al-O-Al bridges.
