Synthesis and spectral properties of lanthanide double-decker complexes with tetrabenzoporphyrin and phthalocyanine

Mixed-ligand double-decker complexes containing tetrabenzoporphyrin and phthalocyanine fragments were synthesized by reaction of phthalocyanine dilithium salt with tetrabenzoporphyrin complexes of lutetium, dysprosium, gadolinium, neodymium, and lanthanum. A relation was found between spectral parameters of the obtained sandwich complexes and radii of the central metal ions.

Structural, Electrical, Magnetic, and Spectroscopic Properties of Ring-Oxidized Molecular Metals Produced by Iodination of Metal-Free and Nickel Tetrabenzporphyrins

Detailed studies of the structure, conductivitity, magnetoresistance, optical spectra, and magnetic properties (susceptibility, EPR) for the new molecular metal tetrabenzporphyrin iodide (H2(tbp)I) and the electrical, spectral, and magnetic properties of Ni(tbp)I are reported. Paramagnetic transition-ion impurities were carefully excluded during the synthesis of H2(tbp)I and Ni(tbp)I, and both materials show much higher, metal-like conductivites than previously seen for less-pure Ni(tbp)I. Comparison of the specular reflectance data for Ni(tbp)I and H2(tbp)I allows a distinction between purely ring π-transitions and metal-involved charge-transfer transitions, and the spectra fix the energy levels of the π orbitals involved in conduction. Transport, magnetic, and optical properties show that both H2(tbp)I and Ni(tbp)I are ring-based conductors that have metal-like conductivities, varying as ～1/T. down to ca. 30-40 K. However, the remaining level of defects is higher in the tbp conductors than in H2(pc)I, and whereas the latter is metallic down to the mK temperature range, the defects in the (tbp) compounds localize the conduction electrons at ～10 K (Ni(tbp)I) and ～30 K (H2(tbp)I), leading to transport through one-dimensional variable-range hopping. EPR g-values for H2(tbp)I and Ni(tbp)I are close to that for the free electron and are nearly temperature-independent. The line widths for both samples are extremely narrow and also are nearly temperature-independent. These results show that Ni(tbp)I does not display doubly-mixed valence, as thought earlier: Paramagnetic impurities significantly altered the EPR signals of the prior samples. H2(tbp)I crystallizes in the space group P4/mcc with cell constants of a = 14.173(10) A? and c = 6.463(4) A?. Full-matrix least-squares refinement of 63 variables gave an R index of 0.061 on F02.

Some peculiarities of metal exchange reactions in porphyrin and phthalocyanine complexes

Kinetics of metal exchange reaction Cd(II) → Zn(II) and Cd(II) → Cu(II) in Cd complexes with tetraphenylporphyrin in DMSO is studied. Reaction with Cu(II) nitrate occurs in both cases more vigorously as compared to that with Zn(II) nitrate. Conditions for metal exchange reactions are studied depending on the nature of metal porphyrinate, a salt (nitrates, acetates, and chlorides of Zn(II), Cu(II), and Co(II), and of organic solvent (DMSO, CH 3CN). It is shown that Zn(II) complexes with nonplanar porphyrins do not show metal exchange Zn(II) → Cu(II) or Zn(II) → Co(II) under mild conditions in DMSO and CH3CN.

Complexation of tetraphenyltetrabenzoporphine with Cu(II), Cd(II), Zn(II), and Co(II) salts in organic solvents

The rate and activation parameters of tetraphenyltetrabenzoporphine (H 2TPTBP) complexation with 3d-metal acetates and acetylacetonates are shown to be determined by the solvent nature. With an increase in the electron-donor properties of a solvent, the reaction rate increases due to protonation of N-H bonds and decreases as MAm(Solv)n - m salt solvates become more stable. As the result, the rate of a reaction with ZnAc2 increases in the series: DMF 3CN 6H6. In inert and weakly coordinating solvents, the transition state of a reaction is supposed to be formed according to the mechanism of contraction of the salt coordination sphere. The rate of H2TPTBP reaction with metal acetates in pyridine changes in the series: Cu(II) > Cd(II) > Zn(II) > Co(II), while the stability of the obtained complexes decreases in the series Cu(II) > Co(II) > Zn(II) > Cd(II). It is shown that the spectral criterion of the complex stability can be used in the series of metal complexes with one ligand, but it is violated if the ligand structure is changed.

Complex formation and spectral properties of meso- phenyltetrabenzoporphyrins in pyridine and N,N-dimethylformamide

Contributions of structural (macroring distortion) and polarization (in asymmetrically substituted derivatives) effects into the reactivity and chromophoric properties of substituted porphyrins were revealed on the basis of the kinetics of complex formation of nona-, deca-, undeca-, and dodecasubstituted porphyrins (meso-phenyltetrabenzoporphyrins) with Zn(OAc) 2 in pyridine and the electronic absorption spectra of the ligands and their complexes with Zn(II) and Cu(II) in pyridine and N,N-dimethylformamide (DMF). Dodecaphenyl substitution produces a weaker ring distortion in the more aromatic tetrabenzoporphyrin compared with porphyrins themselves. Irrespective of the degree of macroring nonplanarity, the Zn (II) and Cu complexes of tetrabenzoporphyrins with increasing degree of meso-phenyl substitution meet a spectral stability criterion.

Effect of a proton-donating solvent on the complexation of classical and nonclassical porphyrins in a pyridine medium

The inhibitory effect of proton-donating additives (HAc) on the rate of coordination reaction (1) of tetrabenzoporphine (H2TBP, I), tetraphenyltetrabenzoporphine (H2TPTBP, II), and N-substituted porphyrins III and IV in pyridine was established. The N-H bonding state in compounds I and II and the reactivity of these compounds in reaction (1) were shown to be similar to those of nonclassical porphyrins (H2P), whereas N-substituted porphyrins apparently do not belong to this group. The inhibition of reaction (1) in the case of compounds III and IV is due to the high basicity of the tertiary nitrogen atoms in these molecules.

Distortion and aromatization factors on the complexing ability of tetrapyrrole macrocycles in acetonitrile

The kinetics of complexation between porphyrins and zinc acetate in acetonitrile was studied for the porphyrins belonging to various structural groups, including aza-, benzo-, and distorted N- and multiply substituted macrocycles. The effects of the distortion, on the one hand, and the enhanced rigidity of a macrocycle, on the other, on the complexation process were considered. The coordination of the distorted porphyrins to metal salts is facilitated because of the disturbance of the steric component of the macrocyclic effect (MCE), whereas the complexation of the rigid macrocycles is facilitated because of the activation of the electronic component of MCE.
