A Topological Investigation of the Nonlinear Optical Compound: Iodoform Octasulfur
Bibliographic record
Abstract
The crystal structure of the nonlinear optical material, iodoform octasulfur (CHI3.(S8)3), in the polar space group R3m, has been shown to contain three unique S...I and several S...S close contacts (<or= 4.0 A), that fall well below the sum of the van der Waals radii of the two atoms concerned. These interactions have all been characterized topologically following the multipole refinement of the crystal structure of iodoform octasulfur. The natures of the possible charge transfer (S...I) and electrostatic (S...S) interactions in this molecule have been investigated based on charge density studies. The properties of the electron density at the bond critical points provide a tool for determining which of the sulfur or iodine atom acts as the donor and which acts as the acceptor in each of the possible S...I charge-transfer interactions present in this molecule. This all leads to a better understanding of the donor/acceptor nature for both types of atoms in charge-transfer complexes of inorganic nonlinear optical materials. The analysis of the structure of iodoform octasulfur has also provided new insight into the relationship between charge density studies and VSEPR theory.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
