Photocatalytic activity in graded off-valent cations substituted NaNbO3

open access: yesHeliyon
This study investigates the impact of off-valent doping on the photocatalytic properties of NaNbO3 concerning the degradation of Methylene Blue. Compositions with x values of 0.00 (representing pure NaNbO3, denoted as NBO) and 0.05 within the material ...

The Interaction Strength, Frequency-shifts and Covalence of the C2H4O∙∙∙HOCl and C2H5N∙∙∙HOCl Heterocyclic Complexes

open access: yesOrbital: The Electronic Journal of Chemistry, 2017
A theoretical study of the structural parameters, electronic properties and vibration modes of the C2H4O∙∙∙HOCl and C2H5N∙∙∙HOCl complexes. The great particularity of these complexes is the O–Cl s-hole, which is considered a proton donor center due to ...

Synthesis, Characterisation, Crystal Structure, DFT, and Hirshfeld Surface Study of a Slightly Distorted Tetrahedral Zn(II) Complex Based on Triphenylphosphanol [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering
An intriguing novel complex, [ZnCl2(Ph3POH)2], containing two equivalents of triphenylphosphanol (Ph3POH), was synthesized by reacting anhydrous ZnCl2 with triphenylphosphine in methanol, yielding a dichlorobis(triphenylphosphanol)-zinc(II) complex with ...

Strain‐Release Pentafluorosulfanylation of Carbonyl‐Containing Disubstituted Bicyclobutanes: A Fortuitous Path to SF5‐Containing Oxa[2.1.1]bicyclohexanes

open access: yesAngewandte Chemie, EarlyView.
A regio‐ and diastereoselective method for strain‐release pentafluorosulfanylation of carbonyl‐containing 1,3‐disubstituted [1.1.0]bicyclobutanes (BCBs) was developed that led to several fortuitous discoveries. For instance, the resultant SF5‐cyclobutanes (SF5‐CBs) exhibit close SF5⋯C═X contacts (X = C, N, O) and provide synthetic access to a new class

Adsorption behavior of the Al- and Ga-doped B12N12 nanocages on COn (n=1, 2) and HnX (n=2, 3 and X=O, N): A comparative study [PDF]

open access: yesChemical Review and Letters, 2019
In this work, density functional theory (DFT) calculations at the M06-2X/6-31+G* level are performed to the adsorption of COn (n=1, 2) and HnX (n=2, 3 and X=O, N)molecules onto pristine as well as Al- and Ga-doped B12N12 nanocages. We study the effect of

[O─I─O]+ Halogen‐Bonded Complexes of Pyridine N‐Oxides

open access: yesAngewandte Chemie, EarlyView.
The missing puzzle of 3‐center‐4‐electron halogen‐bonded complexes viz. [O─I─O]+ of pyridine N‐oxides are structurally characterized by x‐ray diffraction. Monodentate N‐oxide O‐atom acts as the halogen bond acceptor. Their solution complexations are characterized by 15N NMR spectroscopy.

Theoretical Study of Heteroatom Resonance-Assisted Hydrogen Bond: Effect of Substituent on π-delocalization [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2010
The concept of Resonance Assisted Hydrogen Bond (RAHB), which usually occurs in b diketons, has a remarkable role in chemistry. These molecules, which contain heteroatom particularly O and N, are species with biological interest in protein folding and ...
