Binuclear Metal Complexes. VI. Syntheses and Properties of Binuclear Copper(II) Complexes of 2,6-Bis[N-(β-dialkylaminoethyl)iminomethyl]-4-methylphenol
TL;DR: In this paper, a new series of binuclear copper(II) complexes, [Fsal(=NenNR2)2Cu2X]2+ (R=Me and Et, X=Cl, Br, and OH), were synthesized, where Fsal( = NenNR 2)2 indicates the Schiff base prepared from 2,6diformyl-4-methylphenol and N,N-dialkylethylenediamine (alkyl=methyl(Me) and ethyl(Et)).

Characterization and classification of ‘tervalent nickel complexes’, Ni(diamine)2ClX2 (X = Cl and CIO4)
TL;DR: In this article, the ESR, magnetic susceptibilities, IR and electronic spectra, and electric conductivities of solid state were measured for a series of nickel complexes of the general formula Ni(diamine) 2 ClX 2 which appeared to contain "tervalent nickel" in order to elucidate to oxidation state of the nickel.

Synthesis and crystal structure of 1: 2 molecular complexes of bis(N-alkyl-2-oxy-1-napthylideneaminato)copper(II) and -nickel(II) with 7,7′,8,8′-tetracyanoquinodimethane
TL;DR: In this paper, the 1:2 molecular complexes of bis(N-alkyl-2-oxy-1-napthylideneaminato)copper and -nickel with 7,7, 8,8 -tetracyanoquinodimethane (TCNQ) have been prepared and characterized.

Factors Affecting: the Line-width of Nitrogen Superhyperfine Structure in the ESR Spectra of Copper(II) Complexes
TL;DR: In this article, the authors measured the ESR spectra of several series of copper(II) complexes in an attempt to find the best-observable condition for 14N-superhyperfine structure.
