　　Summary:
　　Pyridine diimine metal complexes as catalysts in the light and has excellent performance in recent years has aroused widespread concern. In this paper, different substituted pyridine diimine ligands synthesized two pyridine diimine complexes and five rare earth manganese Neodymium Magnets complexes of the synthesized complexes were structural characterization, and study the luminescence properties of rare earth complexes .
　　The use of 2,6 - diacetyl pyridine are replaced with six different aniline, synthesize 2,6 - [1 - (phenyl imino) ethyl] pyridine (L1), 2,6 - bis [1 - (2 - methyl-phenyl imino) ethyl] pyridine (L2), 2,6 - bis [1 - (2,6 - dimethyl-phenyl imino) ethyl] pyridine (L3), 2, 6-- bis [1 - (2,4,6 - trimethyl-phenyl imine) ethyl] pyridine (L4), 2,6 - bis [1 - (2,6 - diethyl phenyl imine) B yl] pyridine (L5) and 2,6 - [1 - (2,6 - isopropyl phenyl sulfoxide amine) ethyl] pyridine (L6) of six ligands, and characterized by elemental analysis and IR spectroscopy. test methods for the synthesis of the six ligands of the structural characterization.
　　L6 were synthesized using chloride and samarium and europium chloride in acetonitrile was synthesized from the corresponding two rare earth complexes Sm (L6) Cl3 (Sm6) and Eu (L6) Cl3 (Eu6), by elemental analysis and infrared spectroscopy was carried out structural characterization, the two complexes also studied the solid-state light-emitting http://www.everbeenmagnet.com/en/products/110-sintered-neodymium-magnets properties of the two complexes show the characteristic emission of rare earth ions.
　　Using the synthetic L1 ~ L5 and manganese chloride in acetonitrile was synthesized five corresponding manganese metal complexes Mn (L ~ 1) C_ (l2) · 1.5CH_3CN (Mn1), Mn (L ~ 2) C_ (l2) · CH_3CN (Mn2), Mn (L ~ 3) C_ (l2) · CH_3CN (Mn3), Mn (L ~ 4) C_ (l2) · CH_3CN (Mn4) and Mn (L ~ 5) C_ (l2) · CH_3CN (Mn5), on five complexes were characterized by elemental analysis and infrared spectra of structural characterization, and Mn1, Mn3, Mn4, and Mn5 four kinds of complexes develop into single crystal, single crystal XRD test their the crystal structure of the four complexes are shown to approximate CS manganese-centered distorted trigonal bipyramid symmetry configuration.
