Synthesis and EPR Studies of Copper Metal Complexes of Dyes Derived from Remazol Red B, Procino Yellow, Fast Green FCF, Brilliant Cresyl Blue with Copper Acetate Monohydrate

Abstract

The synthesis and characterization of four new solid dye complexes, CuL2(L= 2-[2-methoxy-5-(propane-1-sulfonyl)-phenyl azo]-naphthalen-1-ol, 5-{[3-(4,6-dihydroxy-[1,3,5]tri azine-2-ylamino)-phenyl]-hydrazones}-1-ethyl-4-methyl-2,6-dioxo-1,2,5,6-tetrahydro-pyridine-3-carboxylic acid diethylamide, 4-{bis-[4-(benzyl-ethyl-amino)-phenyl]-methyl}-phenol and 7-imino-4-methyl-7H-phenoxazine-1,3-diamine) is reported. The mode for ligand coordination has been determined by IR and EPR spectra. The carboxyl and amino group of dyes coordinates to the Cu(II) atom as a unidentate or as a chelating ligand.

Synthesis, Spectral and Dyeing Performance Studies of 4-(2-Aminmo-5-nitro-phenylazo)-1,5-dimethyl-2-phenyl-1,2-dihydro-pyrazol-3-one Complexes with Some Metal Ions

“…The FT-IR spectral data of the ligand and all complexes are listed in Table-2. The IR spectrum of the ligand exhibited bands at 3388 and 3377cm -1 ascribed to the υ(NH 2 ) stretching vibration [15], on coordination with metal ion, these bands were observed with a high change in the shape and locale. Strong band at 1716 cm -1 in the ligand spectrum referred to υ(C=O) vibration, change in the intensity and in position to lower frequency observed on coordination with metal ion [16].…”

Synthesis and Characterization of a New Azo Ligand Derivative from 4,5-BIS(4-Methoxyphenyl) Imidazol and its Metal Complexes and Biological Activity Study of its PD(II) Complex

“…Azo-transition metal complexes are attracting increasing attention in both fundamental and applied researches, due to their distinctive geometric and electronic characteristics [9,10]. Azotransition metal complexes are distinguished by the ability to obtain novel compounds with a wide range of biological activity, in addition to their low cost [11].…”

Synthesis, spectroscopic characterization, crystal structure and theoretical investigation of two azo-palladium (II) complexes derived from substituted (1-phenylazo)-2-naphtol

“…Transition metal complexes of azo compounds have received increasing interest in both basic and applied research, owing to their peculiar electronic and geometrical characteristics and their relationships with their use in different crucial fields [1][2][3][4], privileged by their low cost.…”
