Synthesis, Molecular Structure and Electrochemical Property of Heteronuclear Complex, [CuZn(fsan)(H_2O)]·2O
Bibliographic record
Abstract
The complex [CuZn(fsan)(H2O)]H2O, where H4(fsan) denotes the binucleating ligand derived from the schiff base N,N-(3-carboxybenzylidene)-ethylenediamine, was synthesized and its crystal structure was determined by single-crystal X-ray diffraction method. This compound crystallizes in monoclinic, space group P21/n with a = 11.695(2), b = 14.646(3), c = 12.265(3) ? ?= 118.46(3), V = 1847.0(6) 3,C18H12CuN2O8Zn, Mr = 513.21, Z = 4,Dc =1.846 g/cm3,(MoK? = 2.502 mm-1,F(000) = 1028,R = 0.0478 and wR = 0.0902 for 2951 observed reflections with I 2(I). The copper atom is coordinated by two nitrogen atoms and two phenolic oxygen atoms in a square-plane manner. The zinc atom is coordinated by two phenolic oxygen atoms, two equatorial carboxyl oxygen atoms and one axial water oxygen atom in a distorted square pyramid. The two metal atoms are bridged by two phenolic oxygens. The electrochemical property of the complex was also investigated.
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.

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.
