Solid State Reactions of Hemin with Basic Substances: Formation of bis and Mixed Complexes
The solid state reactions of hemin with KCN, Na2S ¢ xH2O, arginine, imidazole, 1-methylimidazole, 2-methylimidazole, benzimidazole, and mixtures of these basic reagents were monitored using IR, M¨ossbauer, and XRD techniques. All these basic substances react at the peripheral propionic acid group of...

| Sumario: | The solid state reactions of hemin with KCN, Na2S ¢ xH2O, arginine, imidazole, 1-methylimidazole, 2-methylimidazole, benzimidazole, and mixtures of these basic reagents were monitored using IR, M¨ossbauer, and XRD techniques. All these basic substances react at the peripheral propionic acid group of hemin-forming salts. Binary mixtures of KCN, arginine, imidazole, 1-methylimidazole, 2- methylimidazole, and benzimidazole were found to form complexes with mixed ligands at the iron site of hemin. According to the structural information obtained for these mixed complexes, mechanisms for their formation are proposed. The solid state synthesis and the properties of the obtained products reveal the specifities of the involved ligands. |
