Enantiomeric bis(μ-<i>N</i>,<i>N</i>′-hexamethylenedisalicylaldiminato)dicopper(II) complexes
Bibliographic record
Abstract
The title dimeric complex, bis[micro-2,2'-[hexane-1,6-diylbis(nitrilomethylidyne)]diphenolato-1:2kappa(4)O,N:N',O']dicopper(II),[Cu(2)(C(20)H(22)N(2)O(2))(2)], has been investigated by single-crystal X-ray diffraction, by thermogravimetric analysis and differential scanning calorimetry, and also by FT-IR spectroscopy. Different synthetic and crystallization procedures gave crystals which were quite different in appearance, and it was initially thought that these were different polymorphic forms. Subsequent structure determination showed, in fact, serendipitous preparation of crystals in the P4(1) space group by one method and in space group P4(3) by the other. In these enantiomorphic structures, the Cu atoms have a distorted flattened tetrahedral coordination, with Cu-N and Cu-O distances in the ranges 1.954 (4)-1.983 (4) and 1.887 (4)-1.903 (4) A, respectively.

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.
