Article
We report extensive experimental and theoretical studies on structural and photophysical properties of two new bulky Schiff base dyes 1 and 2, obtained from the reaction of cyclohexylamine with the 5-bromosalicylaldehyde or 2-hydroxy-1-naphthaldehyde. The structure of 1 exhibits the enol-imine form in the solid state and is characterized by a typic...

In this work, we report solvent-induced complexation properties of a new N2S2 tetradentate bis-thiosemicarbazone ligand (H2LI), prepared by the condensation of 4-phenylthiosemicarbazide with bis-aldehyde, namely 2,2’-(ethane-1,2-diylbis(oxy)dibenzaldehyde, towards nickel(II). Using ethanol as a reaction medium allowed the isolation of a discrete mo...
Article
The Cover Feature demonstrates, contrary to the intuition and classical steric‐based perception, the CH⋅⋅⋅HC attraction in ortho‐xylene rotamers. It is revealed, that their stability is rooted in cooperative action of hyperconjugation, aromaticity and intra‐molecular “bay and side‐types” CH⋅⋅⋅HC interactions. More information can be found in the Ar...
Article
It is shown herein that intuitive and text‐book steric–clash based interpretation of the higher energy “ in‐in ” xylene isomer (as arising solely from the repulsive CH∙∙∙HC contact) with respect to the corresponding global‐minimum “ out‐out ” configuration (where the clashing C‐H bonds are tilted out) is misleading. It is demonstrated that the two...
