Journal ArticleDOI
Cu(II) complexes with square pyramidal (N2S)CuCl2 chromophore: Jahn–Teller distortion and subsequent effect on spectral and structural properties
TL;DR: In this article, a tridentate Schiff base ligand, 2-pyridyl-N-(2′-methylthiophenyl)methyleneimine (pmtpm) was synthesized and characterized by various spectroscopic methods and by X-ray crystallography.
Journal ArticleDOI
Shuttling of nickel oxidation states in N4S2 coordination geometry versus donor strength of tridentate N2S donor ligands
Sudip K. Chatterjee,Suprakash Roy,Suman K. Barman,Ram Chandra Maji,Marilyn M. Olmstead,Apurba K. Patra +5 more
TL;DR: Seven bis-Ni(II) complexes of a N(2)S donor set ligand have been synthesized and examined for their ability to stabilize Ni(0, Ni(I), Ni( II) and Ni(III) oxidation states, showing a new UV-vis band at 470 nm.
Journal ArticleDOI
Copper complexes relevant to the catalytic cycle of copper nitrite reductase: electrochemical detection of NO(g) evolution and flipping of NO2 binding mode upon Cu(II) → Cu(I) reduction.
Ram Chandra Maji,Suman K. Barman,Suprakash Roy,Sudip K. Chatterjee,Faye L. Bowles,Marilyn M. Olmstead,Apurba K. Patra +6 more
TL;DR: Copper complexes of the deprotonated tridentate ligand, N-2-methylthiophenyl-2'-pyridinecarboxamide (HL1), were synthesized and characterized as part of the investigation into the reduction of copper(II) o-nitrito complexes into the related copper nitric oxide complexes and subsequent evolution of NO(g) such as occurs in the enzyme copper nitrite reductase.
Journal ArticleDOI
First structural example of a metal uncoordinated mesoionic imidazo[1,5-a]pyridine and its precursor intermediate copper complex: an insight to the catalytic cycle.
TL;DR: Four copper complexes of a tridentate Schiff base ligand, 2-pyridyl-N-(2'-methylthiophenyl) methyleneimine, L(1) have been synthesized and their reactivity towards externally added KSCN was studied.
Journal ArticleDOI
Copper coordinated ligand thioether-S and NO2− oxidation: relevance to the CuM site of hydroxylases
Ram Chandra Maji,Anirban Bhandari,Ravindra Kumar Singh,Suprakash Roy,Sudip K. Chatterjee,Faye L. Bowles,Kamran B. Ghiassi,Milan Maji,Marilyn M. Olmstead,Apurba K. Patra +9 more
TL;DR: The oxidation chemistry of copper complexes chelated by tridentate N2Sthioether, N2Osulfoxide or N2 Osulfone donor sets is studied to gain insight into the coordination site and oxidative activity of the CuM site of hydroxylases.
