Self-assembly of cadmium(II) salt based on 2,3′,5,5′-biphenyl tetracarboxylate with or without various N-donor ligands affords a series of coordination polymers, namely {[Cd1.5(Hbptc)(H2O)4.5]·2H2O}n (1), {[Cd2(bptc)(2,2′-bipy)2]·2H2O}n (2), {[Cd2(bptc)(pyp)2(H2O)2]}n (3), [Cd(H3bptc)2(bip)2]n (4), and {[Cd2(bptc)(bpt)(H2O)]·H2O}n (5), where H4bptc = 2,3′,5,5′-biphenyl tetracarboxylic acid, 2,2′-bipy = 2,2′-bipyridine, pyp = 3-(pyridin-2-yl)pyrazole, bip = 3,5-bis(1-imidazol)pyridine, bpt = 2-[3-(4-pyridinyl)-1H-1,2,4-triazol-5-yl]pyrazine. Their structures were determined by single-crystal x-ray diffraction anal. and further characterized by elemental anal. and IR spectra. Complex 1 shows a 2D helical layer, which is further extended to a 3D supermol. network through inter-layer C-H···O hydrogen bonds and π···π stacking interactions. Complex 2 exhibits a (3,6)-connected (43)2(46.66.83)-kgd topol. Complex 3 possesses a 2D (3,5)-connected (4.5.6)(4.53.64.72) net based on 1D tube-like chains. Complex 4 has a 1D polymeric ribbon containing left- and right-handed helical chains, which are further hydrogen bonded to form a 2D supermol. layer. Complex 5 possesses a 3D (4,5,7)-connected framework. Moreover, the fluorescent properties of 1–5 in the solid state have been investigated. This study involved multiple reactions and reactants, such as 3,5-Di(1H-imidazol-1-yl)pyridine (cas: 1374155-84-6Product Details of 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. This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.Product Details of 1374155-84-6
