Penta‐ and Hexacoordinated Copper(II) Complexes with Azido and 4‐amino‐3,5‐di‐2‐pyridyl‐4H‐1,2,4‐triazole Ligands with Field‐Induced Slow Magnetic Relaxation

ChemistryOpen, EarlyView.
A field‐induced slow magnetic relaxation was observed in an ionic pentacoordinated Cu(II) complex with 4‐amino‐3,5‐di‐2‐pyridyl‐4H‐1,2,4‐triazole and azido ligands. The analysis of the relaxation behaviour supports the origin of the slow magnetic relaxation in intramolecular low‐energy vibration modes participating in the one‐phonon direct and two ...

5-[(E)-Methoxy(phenyl)methylidene]-1,3,4-triphenyl-4,5-dihydro-1H-1,2,4-triazole

Acta Crystallographica Section E, 2012
In the title compound, C28H23N3O, the 1,2,4-triazole ring deviates slightly from planarity adopting a N3TC2 conformation which is distorted towards an EC2 conformation. The plane around the ethylene unit makes a dihedral angle of 17.32 (11)&

A SlMYB78‐regulated bifunctional gene cluster for phenolamide and salicylic acid biosynthesis during tomato domestication, reducing disease resistance

Journal of Integrative Plant Biology, EarlyView.
The tomato transcription factor SlMYB78 controls a key metabolic gene cluster including ENHANCED PSEUDOMONAS SUSCEPTIBILTY 1, encoding a key enzyme that produces disease‐fighting compounds (phenolamides) and immune signals (salicylic acid). During domestication, tomatoes lost a superior variant (SlEPS1HapB), weakening disease resistance; restoring this
