The Crystals Structure And Properties Of The Proton Transfer Coordination Polymers Built From A Pyridazine Schiff Base

In this thesis, we choose a new Schiff base ligand (E)-3-chloro-6-[2-(pyrazin-2-ylmethylene)hydrazinyl]pyridazine (HL) bearing pyridazinyl and pyrazinyl groupsreact with different metal ions by slow evaporation method. Eleven new complexeshave been synthesized:[CuII2L2Cl2](1)[CuII(L-H)(NO3)(H2O)2](NO3)(H2O)(2){[CuII(L-H)(H2O)](ClO4)2(H2O)}n(3)[CuII2L2(OH)](NO3)(H2O)2(4)[CuII2L2(OH)](ClO4)(5)[Mn2(L-H)2Cl4]·CH3CN (6)[Mn(L-H)(NO3)2·CH3OH](7)[Zn(L-H)L](NO3)(8)[Ni(L-H)2](NO3)2·2H2O (9){[Pb(L-H)(NO3)2H2O]H2O}n(10)[Bi(L-H)2(NO3)2]NO3(11)And structural characterized by IR spectra, elemental analyses, the bond valencesum (BVS) analyses, powder X-ray diffraction (PXRD) analyses, X-ray single crystaldiffraction and density function theory calculations (DFT). The DFT analysis,magnetic properties and nano-particle properties of some complexes have beenstudied. The antibacterial and antioxidant activities of all complexes have beenstudied.
