Zeolites versus aluminosilicate clusters: the validity of a local description
Open accessAbstract
A comparison of force field calculations on extended systems and ab initio quantum chemical calculations on ring structures reveals that the relative energy content of neutral-framework silicas and aluminophosphates is determined by that of the smallest substructures. Energy-minimized structures containing only four, five, and six rings have the same energy content to within 10 kJ/mol. Hypothetical three-ring-containing structures have considerably higher energy content, which may well inhibit their synthesis in the pure SiO2 modification. The results accord with sparse experimental information, Using the same combination of techniques, we demonstrate that substitution of aluminum in silica causes an appreciable, albeit local, distortion of the lattice. The relaxation energy for such a substitution amounts to 100 200 kJ/mol, depending on the way charge compensation is accomplished

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.
