Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Molecular Structure called Spectroscopic, Electrochemical, Magnetic and Structural Characterization of an Hexamethylenetetramine Co(II) Porphyrin Complex – Application in the Catalytic Degradation of Vat Yellow 1 dye, Author is Nasri, Soumaya; Hajji, Melek; Guergueb, Mouhieddinne; Dhifaoui, Selma; Marvaud, Valerie; Loiseau, Frederique; Molton, Florian; Roisnel, Thierry; Guerfel, Taha; Nasri, Habib, which mentions a compound: 28903-71-1, SMILESS is COC1=CC=C(C=C1)C(C2=[N]3[Co+2]4([N-]56)[N-]7C(C(C8=CC=C(C=C8)OC)=C3C=C2)=CC=C7C(C9=CC=C(C=C9)OC)=C%10C=CC%11=[N]4%10)=C5C=CC6=C%11C%12=CC=C(C=C%12)OC, Molecular C48H38CoN4O4, Safety of 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II).
In this study, a new cobaltous-(hexamethylenetetramine) [meso-tetra(para-methoxyphenyl)porphyrin complex] with the formula [CoII(TMPP)(HMTA)] (1) was synthesized. The mol. structure was confirmed in solution by 1H NMR spectroscopy and mass spectrometry methods, and the single crystal x-ray diffraction structure of 1 was determined at both room temperature and low temperature This species was further characterized by IR, UV-visible and fluorescence spectroscopies, magnetic susceptibility measurements and cyclic voltammetry. The chem. reactivity behavior was also assessed theor. through D. Functional Theory (DFT) approach. Magnetic investigation indicates that the Co(II)-HMTA porphyrin 1 species at low temperature is a cobaltous low-spin (S = 1/2) species while at high temperature complex 1 exhibits a spin-crossover low-spin (S = 1/2) ↔ high-spin (S = 3/2). The adsorption kinetic of the “”vat yellow 1 dye”” was carried out in aqueous solution at pH = 6. The exptl. results are better fitted using the pseudo second order model. Furthermore, complex 1 was tested as catalyst in the degradation of the vat yellow 1 dye using an aqueous H2O2 solution and by photodegradation under solar light.
In addition to the literature in the link below, there is a lot of literature about this compound(5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II))Safety of 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II), illustrating the importance and wide applicability of this compound(28903-71-1).
