Complexing reactions in the Ni(II)-5-methyl-4-amino-3-thiooxo-1,2,4-triazapentene-1-methanal and Ni(II)-5-methyl-4-amino- 3-thiooxo-1,2,4-triazapentene-1-propanone triple systems |

Abstract: | Complexing processes in the NiII-TTA-methanal (A) and NiII-TTA-propanone (B) triple systems (TTA–5-methyl-4-amino-3-thiooxo-1, 2, 4-triazapentene-1) in ethanol solution and nickel(II)hexacyanoferrate(II) gelatin-immobilized matrix have been studied. In the NiII-TTA- methanal system, formation of NiII oligomeric coordination compounds in which metal chelate cycles are connected by–H2C–O–CH2–structural groups, takes place. In the NiII-TTA-propanone triple system, formation of only NiII complexes with TTA takes place. No complexing process in the triple systems in nickel(II)hexacyanoferrate(II) gelatin-immobilized matrix was found. |
