Synthesis of metal-free and metallophthalocyanines containing 18- and 21-membered macrocycles with mixed donor atoms and their metal-ion binding properties

This paper describes the synthesis of a series of metal-free phthalocyanines and metallophthalocyanines peripherally substituted by macrocycles of different ring sizes with the same donor atom sets. The effects of varying ring size of the macrocycle on the spectroscopic and metal ion binding properties of phthalocyanines were examined. For these purposes, electronic absorption properties for metal-free phthalocyanines and metallophthalocyanines were studied in dimethylformamide and tetrahydrofuran. The liquid-liquid extraction of metal picrates such as Ag(I), Hg(II), Cd(II), Zn(II), Cu(II), Ni(II), Pb(II), and Co(II) from the aqueous phase to the organic phase was carried out using metallophthalocyanines. All new compounds were characterized using several spectroscopic techniques.

Synthesis of (2-hydroxo-5-chlorophenylaminoisonitrosoacetyl)phenyl ligands and their complexes: Spectral, thermal and solvent-extraction studies

Four different types of new ligands Ar[COC(NOH)R] n (Ar=biphenyl, n = 1 H2L1; Ar=biphenyl, n = 2 H 4L2; Ar=diphenylmethane, n = 1 H2L3; Ar=diphenylmethane, n = 2 H4L4; R=2-amino-4-chlorophenol in all ligands) have been obtained from 1 equivalent of chloroketooximes Ar[COC(NOH)Cl] n (HL1-H2L4) and 1 equivalent of 2-amino-4-chlorophenol (for H2L1 and H 2L3) or 2 equivalent of 2-amino-4-chlorophenol (for H 4L2 and H4L4). (Mononuclear or binuclear cobalt(II), nickel(II), copper(II) and zinc(II) complexes were synthesized with these ligands.) These compounds have been characterized by elemental analyses, AAS, infra-red spectra and magnetic susceptibility measurements. The ligands have been further characterized by 1H NMR. The results suggest that the dinuclear complexes of H2L1 and H2L3 have a metal:ligand ratio of 1:2; the mononuclear complexes of H4L2 and H4L4 have a metal:ligand ratio of 1:1 and dinuclear complexes H4L2 and H4L4 have a metal:ligand ratio of 2:1. The binding properties of the ligands towards selected transition metal ions (Mn II, CoII, NiII, CuII, Zn II, PbII, CdII, HgII) have been established by extraction experiments. The ligands show strong binding ability towards mercury(II) ion. In addition, the thermal decomposition of some complexes is studied in nitrogen atmosphere.

Synthesis and characterization of some mixed-ligand picrate complexes of nickel(II) involving heterocyclic nitrogen donors

The present communication describes the synthesis of some mixed-ligand hexacoordinated picrato complexes of nickel(II) of the composition [Ni(PA)2(L-L)2], where PAH = picric acid and L-L = 2-aminoben-zothiazole (ABZT), 2-(2′-aminophenyl)benzothiazole (2′-AMPHBZT), 2-(3′-aminophenyl)benzothiazole (3′-AMPHBZT), bipyridine (bpy), o-phenanthroline (phen) or 2,6-bis(benzimidazyl)pyridine (BBZLPY). These complexes were obtained by the interaction of nickel(II) picrate with the corresponding ligands L-L in methanol. The resulting compounds have been characterized by elemental analyses, magnetic, molar conductance and decomposition temperature measurements, electron spin resonance, infrared and electronic spectral studies. All the complexes are thermally stable and behave as non-electrolytes. An octahedral structure has been tentatively proposed for these complexes.

Synthesis and characterization of some transition metal picrate complexes with isonicotinic acid hydrazide

The mixed ligand complexes of Cr(III), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) picrates with isonicotinic acid hydrazide (INH) of the type (where n = 1, 2 or 3) have been prepared and characterized by elemental analysis, conductance, molecular weight, magnetic susceptibility, electronic, IR and EPR spectra.The investigations indicate that metal ions have octahedral structure but low symmetry distortion exists in some cases.

Crown thioether chemistry: Homoleptic hexakis(thioether) complexes of nickel(II)

The Ni(II) complexes of 1,4,7,10,13,16-hexathiacyclooctadecane (18S6, hexathia-18-crown-6), 2,5,8-trithianonane, 1,5,9-trithiacyclododecane (12S3, trithia-12-crown-3), and 1,5,9,13,17,21-hexathiacyclotetracosane (24S6, hexathia-24-crown-6) have been synthesized and characterized by single-crystal X-ray diffraction and electronic spectroscopy. Each of these complexes contains a high-spin [Ni(thioether)6]2+ cation with octahedral microsymmetry. Comparison of these complexes shows that within a conserved coordination sphere the different ring sizes (1) change the Ni-S distances by up to 0.05 ?, (2) affect the ligand field splitting by up to 10%, and (3) greatly influence the stability of the resulting complexes.
