Preparation and structure of 2-(2-benzimidazol-2-yl)pyridine N-oxide and its complexes

Diaquabis[5-(1-oxidopyridin-1-ium-2-yl)-1,2,3,4-tetrazolido]manganese(II) dihydrate

“…1). In the mononuclear unit, manganese(II) ion is in a distorted octahedral environment, being six-coordinated by two N atoms and two O atoms from two bidentate 5-(2-pyridyl-1-oxide)tetrazolato-ligands, and two O atoms of two coordinated water molecules with Mn-O distances from 2.090 (4)Å to 2.209 (3) Å, Mn-N bond length of 2.255 (4)Å and O1-Mn1-N1 angle of 79.47 14°, which are comparable with the values observed in other metal-tetrazolate complexes (Vrbova et al, 2000;Lin et al, 2005;Facchetti et al, 2004)…”

Synthesis and Antibacterial Studies of Metal Complexes of Cu(II), Ni(II) and Co(II) with Tetradentate Ligand

“…The magnetic susceptibility of Co(II) complex is 4.3 B.M [14], which denotes to an octahedral geometry. The magnetic susceptibility of Ni(II) complex, 3, is 0.06 B.M, which indicates a square-planar geometry [15].…”

Sublimation Enthalpies of Substituted Pyridine N-Oxides

“…According to numerous studies, the biochemical activity of heterocyclic N- oxides is directly related to complex formation in living organisms [ 12 – 14 ]. Complexes of N- oxides with d -metals have magnetic properties [ 15 , 16 ]. In addition, N- oxides are promising reagents for the extraction of metal ions.…”
