Complexes of copper(II) with diazabutadienes

Transition Metal Chemistry, 1987
Studies on the chelate complexes of copper(II) with the bidentate ligands, 1,4-diphenyl-2,3-dimethyl-1,4-diazabutadiene (PMB) and 1,4-di(p-methoxyphenyl)-2,3-dimethyl-1,4-diazabutadiene (MPMB), have been carried out. On the basis of the elemental analysis and molar conductivity, the complexes have been characterized as [Cu(PMB)Cl2], [Cu(PMB)2](ClO4)2, [

Benzoylacetanilide complexes of copper(II)

Journal of Inorganic and Nuclear Chemistry, 1975
Abstract The synthesis of twenty copper(II) complexes of benzoylacetanilides variously substituted in the anilide ring, is described. Their general formula is [CuL2] (L = 3- or 4-substituted benzoylacetanilide anion. Contrary to an earlier report, the complexes have normal magnetic moments (μeff ∼ 1·8 B.M. at 295 K).

Complexes of copper(II) with the ephedrines

Journal of Inorganic and Nuclear Chemistry, 1971
Abstract Two new complexes of copper(II) with (+)-pseudoephedrine ((+)-Hψ-eph) have been isolated and characterised as [Cu((+)-ψ-eph)2] · (+)-Hψ-eph · 2H2O (confirmed by a recent crystal structure analysis) and as [Cu((+)-ψ-eph)2]3. The results are compared with those for the diastereoisomeric ligand ephedrine.

Copper(II) complexes of hydrazides

Journal of Inorganic and Nuclear Chemistry, 1981
Abstract The Cu(II) complexes of three hydrazides of aspartic and glutamic acids have been obtained and studied using electronic IR and EPR spectra, DTA, magnetic susceptibility measurements, extraction, ion exchange and elemental analysis data. It was found that depending on the reaction conditions two types of complexes are obtained, with M:L ...

Copper(II) complexes of benzimidazole

Journal of the Chemical Society A: Inorganic, Physical, Theoretical, 1966
The preparation and spectral and magnetic properties are reported for complexes of the type Cu(benzimidazole)4X2(X = Cl, Br, NO3, ClO4, NCS, and ½SO4). These have tetragonally distorted octahedral structures, and the “inner complex” Cu(C7H5N2)2 contains copper ions in a distorted tetrahedral environment. An unstable acetatocomplex may be of the dimeric

Complex carbonates of copper(II)

Journal of Inorganic and Nuclear Chemistry, 1974
Abstract The visible absorption spectra for a copper(II) salt dissolved in (i) (NH4)2CO3 and (ii) in a mixture of K2CO3 and KHCO3 show absorption maxima at 650 nm for (i) and 690 and 720 nm for (ii). Methods for the preparations of (a) Na3[Cu2(CO3)3OH]. 4H2O, (b) Rb[Cu2(CO3)2(OH)]. 6H2O, (c) K[CH5N3H][Cu(CO3)2].
