2,2'-Bipyridine Complexes. I. Polarized Crystal Spectra of Tris (2,2'-bipyridine)copper(II), -nickel(II), -cobalt(II), -iron(II), and -ruthenium(II)

NMR, ESR, NQR and IR Studies of Paramagnetic Macrocyclic Complexes of 1st Transition Series Metal Ions Exhibiting MLCT Phenomenon: A DFT Application. Part: III. Tris (2, 2- bipyridine) Complexes

“…So It was difficult to assign exact value to  CN because several free 2, 2  -bipyridine vibrations would also fall in the  CN region {Hutchinson et al tried metal isotope technique in Table: 1 showed the thermal parameters of the studied complexes. 14 N, 13 C, and 1 H of the three complexes. Table: 4 showed 10 Diamagnetic, Paramagnetic and Spin orbit contributing terms in σ values of constituents.…”

“…As many as 13 parameters of three techniques: ESR (g n , A ten ), NQR (NQCC, ) and NMR {σ 13 1 H} given by the software were used to ascertain the stereochemistry of the three paramagnetic complexes by the following two ways:…”

“…This tempted us to take up a few biologically important, analytically suitable and optically active macrocyclic paramagnetic complexes: [L 3 M] 2+ {M=V(II), Ni(II)}, and [L 3 Cr] 3+ where L=2,2  -bipyridine, which were known to exhibit MLCT phenomenon (11)(12)(13). Accurate computations of their NMR, ESR and NQR (14)(15)(16)(17) parameters had become possible by DFT only recently (18)(19)(20).…”

Chemiluminescence Detection of Glucose Using Ce(IV) Oxidation in a Batch System

“…Tris(2,2′-bipyridine)ruthenium(II) chloride (Ru complex, [Ru(bpy)3]Cl2·6H2O) was prepared in our laboratory according to a method reported in the literature. 13 Its sulfate salt was prepared from the chloride form of the Ru complex and Ag2SO4 (sulfonate; C30H24N6O4SRu·8H2O. Found: C, 43.94%; H, 4.47%; N, 10.20%.…”

Simultaneous Detection of Monoethanolamine, Diethanolamine, and Triethanolamine by HPLC with a Chemiluminescence Reaction and Online Derivatization to Tertiary Amine

“…The primary and secondary amine are delivatized by a reaction with epichlorohydrin having an epoxy moiety in a reaction coil to yield a tertiary amine with subsequent chemiluminescence detection using [Ru ( complex used in this work was prepared by a reported method. 17 Analytical-reagent grade chemicals were used throughout. Epichlorohydrin (1-chloro-2,3-epoxypropane) was used as a derivatization reagent, and [Ru(bpy)3]Cl2 solution was used as a CL reagent.…”
