Synthesis, Structures And Characters Of Coordination Polymers Of 1,3-bis(1H-1,2,4-triazol-1-ylmethyl)benzene

The research on synthesis, structure and property of coordination polymer not onlyriches coordination chemistry, but also extends the application field for the compounds inoptics, magnetics and so on.Organic ligand plays an important role in the constructing the coordination polymers.Flexible ligand 1,3-bis(1H-1,2,4-triazol-1-ylmethyl)benzene (btmp) may have differentcoordination modes, due to itself different conformation and freely circumrotatoryσbond. Such ligand has big transfiguration ability, so it can construct various, novelsupramolecular structure and open a new field of the supramolecular chemistry.In the work, we reported ten coordination polymers formed by using flexible ligands1,3-bis(1H-1,2,4-triazol-1-ylmethyl)benzene (btmp) and transition metal cations Cd(â…¡),Cu(â…¡), Mn(â…¡), namely, [Cd(btmp)₂(NSC)₂]_n (1), [Cd(btmp)2Cl₂]_n (2),{[Cd(btmp)₂(H₂O)₂](BF₄)₂}_n (3), [Cu(btmp)₂(NCS)₂]_n (4), [Cu(betc)_0.5(btmp)]_n (5),[Cu(btmp)₂Cl₂]_n (6), [Mn(btmp)₂(NCS)₂]_n (7), [Mn(btmp)₂Cl₂]_n (8), [Mn(dca)₂(btmp)₂(H₂O)]_n (9), {[Mn(dca)₂(btmp)₂](btmp)}_n (10). The ten compounds have beencharacterized by elemental analysis, IR Spectra, luminescence analyses and X-raycrystallography and their synthesis are also fully described in this thesis.In shows the flexible ligand usually function as bridge to connect two centers andform one-dimensional helix chain, one-dimensional double-stranded chain,two-dimensional network structure to form stable complexes, the flexible ligand maychange itself conformation.
