A new stable organic metal based on the BEDO-TTF donor and the doubly charged nitroprusside anion, (BEDO-TTF)4[Fe(CN)5NO]
Bibliographic record
Abstract
(BEDO-TTF)4[Fe(CN)5NO] was synthesized by electrocrystallization using the nitroprussides M2[Fe(CN)5NO]·2H2O (M = K, Rb) as supporting electrolytes and TCE (1,1,2-trichloroethane) and DCE (1,2-dichloroethane) as solvents. The crystal structure of this new salt (a = 4.0251(3), b = 15.266(2), c = 19.259(2) Å, α = 97.02(1), β = 93.23(1), γ = 96.04(1)°, V = 1165.1(2) Å3, Z = 3/4, space group P) is characterized by the presence of β″-type radical cation layers and anion layers containing disordered nitroprusside anions. The stoichiometry was confirmed by a micro-Raman spectroscopic study and the band structure and Fermi surface of this new salt were studied by means of the extended Hückel tight binding method. (BEDO-TTF)4[Fe(CN)5NO] is a two dimensional metal stable down to liquid helium temperatures.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
