High-Density Electron Anions in a Nanoporous Single Crystal: [Ca 24 Al 28 O 64 ] 4 + (4 e - )
Abstract
We removed ∼100% of clathrated oxygen ions from the crystallographic cages in a single crystal of 12CaO·7Al 2 O 3 , leading to the formation of high-density (∼2 × 10 21 cm – 3 ) electrons highly localized in the cages. The resulting electron forms a structure that we interpret as an F + center and migrates throughout the crystal by hopping to a neighboring cage with conductivity ∼100 siemens per centimeter, demonstrating that the encaged electron behaves as an anion. The electron anions couple antiferromagnetically with each other, forming a diamagnetic pair or singlet bipolaron. The resulting [Ca 24 Al 28 O 64 ] 4 + (4 e – ) may be regarded as a thermally and chemically stable single crystalline “electride.”

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.
