Synthesis And Properties Of Complexes Based On Pyrimidine And Quinoline

In recent years,coordination compounds especially metal organic framework compounds and metal cluster compounds have become a key research object in coordination chemistry field.Metal coordination compounds have drawn tremendous attention for the reason that it?s intriguing structural topologies and widely potential properties in selective separation,catalysis,gas storage,biomedical imaging and nonlinear optics(NLO).The primary consideration is the choise of ligand and the coordination geometry of the metal,for the main properties is determined by the structure of coordination compounds.In this paper,seven coordination componds were constructed successfully by the solvothermal method.The coordination mode,optics properties and magnetic properties has been described.The main contents are summarized as follows:1.The assembly of asymmetric bis(chelating)2-pyrimidinecarboxylate(2-PmC)with MnII ions produced two transition metal coordination polymers through the in situ hydrolytic transformation reaction of 2-Cyanopyrimidine(2-PmCN),has been solvothermal synthesized.In 2D layer [MnCl(L)H2O]n(1)the six member Mn rings constructed by MnII ions and L ligands was connected to each other by double chloride anions.And using the formate to substitute partly of the chloride anions an two interpenetrated srs-Net [Mn2Cl1.5L2(HCO2)0.5]n(2)was obtained.In the srs-net the L ligands bridged MnII to give a 1D chain,that was further connected by the double chloride anions and Cl/formtae bridges in forming srs-nets which is two-fold interpenetrated.Interesting 2 exhibits obvious second-harmonic generation(SHG)response of approximately 0.8 time of KH2PO4(KDP).2.Five new 3d-4f metal cluster compounds based on 8-hydroxyquinoline have been successfully obtained under solvothermal.And the characterization based on crystal XRD.Then,the catalytic activity of compound 6 exploration,which can catalytic the reaction between 2-furaldehyde and morpholine led to a quantitative amount of(4S,5R)-dimorpholinocyclopent-2-enone.Test the magnetic of compounds 7,explain Er4Ni9 clusters is ferromagnetic.
