Two Zn coordination polymers {[Zn(ic)(bip)]ยท2H2O}n (1) and [Zn(ic)(bpe)]n (2) [H2ic = itaconic acid, bip = 3,5-bis(1-imidazoly)pyridine and bpe = 1,2-bi(4-pyridyl)ethylene] were synthesized hydrothermally and characterized structurally by single-crystal x-ray diffractions and elemental anal. Both complexes 1 and 2 displayed 2-dimensional (4,4) grid layers containing 1-dimensional metal-carboxylate chains. Thermogravimetric Analyses (TGA), powder x-ray diffractions (PXRD) and fluorescence properties for compounds 1 and 2 were also studied. The solid state fluorescence spectra indicated that the emission spectrum of complex 1 showed obvious blue shift (-78 nm) compared to free bip co-ligand due to the ligand-to-metal charge-transfer (LMCT) effect. The compound 2 showed similar emission spectrum to the free bpe ligand, but the slight red shift might be attributed to the complexation effect between the bpe mol. and Zn atoms. This study involved multiple reactions and reactants, such as 3,5-Di(1H-imidazol-1-yl)pyridine (cas: 1374155-84-6HPLC of Formula: 1374155-84-6).
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. The pharmacophore of imidazole exists in bioactive compounds including amino acids, plant growth regulators and therapeutic agents.n increase of the alkyl chain length of the alcohols.
