Using multidenate 4,4′-(phenylazanediyl)dibenzoic acid (H2L) and 1,3-bis(imidazol-1-yl)benzene (B), 3,5-bis(imidazol-1-yl)pyridine (bimp) or 1,4-bis(imidazol-1-yl)benzene (B’) as ligands under solvothermal conditions, three new metal-organic frameworks with interpenetrating structure, {[CoLB]·H2O}n (1), {[Co2L2(bimp)0.5]·3H2O}n (2) and {[Co2L2B’2]·2DMF}n (3), were synthesized. The complexes were characterized by single-crystal X-ray diffraction (XRD), thermal anal. and powder X-ray diffraction (PXRD). Complexes 1–3 all crystallize in the monoclinic system, with C2/c(complex 1), P2/n(complex 2) and P21(complex 3) space group, resp. In complexes 1 and 3, Co2+ forms a tetracoordinate geometry, whereas it forms a five-coordinated geometric configuration and exists as a dual-core paddle-shaped structural unit [Co2(CO2)4] in complex 2. Complexes 1 and 2 give a 2-fold interpenetrating three-dimensional (3D) supramol. networks, while complex 3 exhibits a 4-fold interpenetrating 3D framework. The results of electrochem. studies show that complexes 1–3 are electrochem. active substances with good electrochem. reversibility. This study involved multiple reactions and reactants, such as 3,5-Di(1H-imidazol-1-yl)pyridine (cas: 1374155-84-6Quality Control of 3,5-Di(1H-imidazol-1-yl)pyridine).
3,5-Di(1H-imidazol-1-yl)pyridine (cas: 1374155-84-6) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Quality Control of 3,5-Di(1H-imidazol-1-yl)pyridine
