A novel bisperoxovanadium complex, [NH4][VO(O2)2(ima)] (1) (ima = imidazole-4-carboxamide), was synthesized by the reaction of NH4VO3 and ima in the presence of H2O2, and the structure was characterized by single-crystal x-ray technol. The adjacent [NH4][VO(O2)2(ima)] monomers further constructed a 3D supramol. framework through intra- and intermol. H bonding interactions. The composition of the title complex solution was explored using a combination of multinuclear (1H, 13C and 51V) magnetic resonance, heteronuclear single quantum coherence (HSQC), and variable temperature NMR in a 0.15 mol L-1 NaCl/D2O solution that mimics physiol. conditions. According to NMR exptl. results, a pair of isomers (A and B) are observed in aqueous solution, which are attributed to different types of coordination modes between the metal center and the ligands; Isomer B (the main product) has the same coordination structure as the crystal structure of [NH4][VO(O2)2(ima)]. The 51V NMR experiment together with single-crystal x-ray diffraction results indicated that Isomer A is the hexacoordinated peroxovanadium species while Isomer B is the heptacoordinated species. In the experiment, the researchers used many compounds, for example, 1H-Imidazole-4-carboxamide (cas: 26832-08-6Application of 26832-08-6).
1H-Imidazole-4-carboxamide (cas: 26832-08-6) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Application of 26832-08-6
