1,4,8,11-Tetraazoniacyclotetradecane tetrakis(phenylphosphonate) dihydrate forms hydrogen-bonded sheets
Bibliographic record
Abstract
In the title compound, C(10)H(28)N(4)(4+).4C(6)H(6)O(3)P(-).2H(2)O, the cation lies across a centre of inversion in space group P2(1)/n. The two independent anions and the water molecule are linked by four O-H.O hydrogen bonds [H.O = 1.74-2.15 (3) A, O.O = 2.5482 (14)-3.0438 (16) A and O-H.O = 160-176 (2) degrees ] into sheets containing equal numbers of centrosymmetric R(6)(6)(16) and R(10)(10)(36) rings. The cation lies at the centre of the R(10)(10)(36) ring and is linked to it by eight N-H.O hydrogen bonds [H.O = 1.77-1.98 A, N.O = 2.6756 (15)-2.8168 (16) A and N-H.O = 151-169 degrees ].
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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.
