Kinetic Evidence for Five-Coordination in AlOH(aq) 2+ Ion
Abstract
Trivalent aluminum ions are important in natural bodies of water, but the structure of their coordination shell is a complex unsolved problem. In strong acid (pH < 3.0), Al III exists almost entirely as the octahedral Al(H 2 O) 6 3+ ion, whereas in basic conditions (pH > 7), a tetrahedral Al(OH) 4 – structure prevails. In the biochemically and geochemically critical pH range of 4.3 to 7.0, the ion structures are less clear. Other hydrolytic species, such as AlOH(aq) 2+ , exist and are traditionally assumed to be hexacoordinate. We show, however, that the kinetics of proton and water exchange on aqueous Al III , coupled with Car-Parrinello simulations, support a five-coordinate Al(H 2 O) 4 OH 2+ ion as the predominant form of AlOH(aq) 2+ under ambient conditions. This result contrasts Al III with other trivalent metal aqua ions, for which there is no evidence for stable pentacoordinate hydrolysis products.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
