Syntheses, Crystal Structure And Properties Of Complexes Based On V-shaped And Linear N-containing Ligands

In this paper, by using V-shaped N-containing pyridyl ligand L1= 4,4’-(oxybis(4,1-phenylene))dipyridine and linear 1,4’-bisbenzimidazole benzene (L2), 1-(4-(1H-imidazol-1-yl)phenyl)pyridin-1-ium-4-olate (L3) and Cu(NO3)2-3H2O, CuCl2·2H2O, CoCl2·6H2O, Ni (NO3)2·6H2O, Cd (NO3)2·4H2O, we have successfully synthesized ten complexes by solvothermal method.(1) [Cu(L1)(1,3-bdc)]n(2) [Cd(L1)2(trans-chdc)2]n(3){[Co(L1)3(Hbptc)2(H2O)2]·2H2O}n(4) [Cu(L1)(Cl)]n(5) [Co(L1)(hfipbb)2]n(6){[Cd(Ll)2(tda)(H2O)]·H2O}n(7) [Ni(L1)2(bda)(H2O)2]n(8) [Co(L2)1/2(btc4-)]n(9) [Co(L2)(btc2-)(H2O)2]n(10){[Co(L3)(oba)(H2O)]·H2O}n1,3-H2bdc= isophthalic acid, trans-chdc=trans-1,4-cyclohexanedicarboxylic acid, H4bptc= 3,3’-4,4’-biphenyl tetracarboxylic acid, H2hfipbb =4,4’-(perfluoropropane-2,2-diyl)dibenzoic acid, H2tda= 2,5-thiophenedicarboxylic acid, H2bda= [1,1’-biphenyl]-4,4’-dicarboxylic acid, H4btc= 1,2,4,5-benzenetetracarboxylic acid, H2btc= terephthalic acid, H2oba= 4,4’-oxydibenzoic acidThese complexes were characterized by IR, elemental analysis, single crystal X-ray diffraction, XRD, Uv-vis, thermogravimetric analysis.
