Synthesis and structures of divalent Co, Ni, Zn and Cd complexes of mixed dichalcogen and dipnictogen ligands with corrosion inhibition properties: experimental and computational studies

Abstract

The structural and corrosion inhibition properties of four different transition-metal complexes of heteroleptic S-donor atom dithiophosphonate and N-donor atom phenanthroline ligands are reported.

Effective corrosion inhibition of mild steel in hydrochloric acid by newly synthesized Schiff base nano Co(ii) and Cr(iii) complexes: spectral, thermal, electrochemical and DFT (FMO, NBO) studies

“… 70,71 The calculated band gap for Co( ii )-L and Cr( iii ) complexes are 1.824 and 2.969 eV, respectively ( Table 8 ) in good agreement with the calculated band gap of Co, Zn, Cd and Ni complexes which are 1.109, 1.458, 1.535 and 2.352 eV, respectively. 72 The narrow band gap of Co( ii )-L and Cr( iii )-L complexes reflects high reactivity and therefore a strong interaction with mild steal surface and good adhering capabilities.…”

The effect of structural configuration on the DNA binding andin vitroantioxidant properties of new copper(ii) N2O2Schiff base complexes

“…67,68 B3LYP functional with 6-31+G(d,p) basis was applied for ligand atoms and LANL2DZ for the central metal ions. 67 The synergy between this functional and basis set has been reported 69 to be suitable for compounds containing metal ions. 70 True energy minima were verified by performing frequency calculation for all complexes with no indication of imaginary frequencies.…”

Heptanuclear Silver Hydride Clusters as Catalytic Precursors for the Reduction of 4-Nitrophenol

“…[Ag(CH 3 CN) 4 ]PF 6 [53] and NH 4 [S 2 P(4-C 6 H 4 OMe)(OR)] derivatives [54,55] were prepared following literature procedures. NMR spectra were recorded on a Bruker AV-400 instrument (Billerica, MA, USA) operating at 400MHz.…”
