Crystal Structure and Optical Properties of Cd 32 S 14 (SC 6 H 5 ) 36 . DMF 4 , a Cluster with a 15 Angstrom CdS Core
Abstract
Recrystallization of the solid Cd 10 S 4 (SC 6 H 5 ) 12 from a solution of pyridine and N , N -dimethylformamide (DMF) results in the formation of the cluster Cd 32 S 14 (SC 6 H 5 ) 36 ⋅DMF 4 as pale yellow cubes. The structure consists of an 82-atom CdS core that is a roughly spherical piece of the cubic sphalerite lattice ∼12 angstroms in diameter. The four corners of the lattice are capped by hexagonal wurtzite-like CdS units, which results in an overall tetrahedral cluster ∼15 angstroms in diameter. This cluster dissolves intact in tetrahydrofuran where its absorption spectrum reveals a sharp peak at 358 nanometers at room temperature and its emission spectra show a strong broad band at 500 nanometers.

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.
