Synthesis,Crystal Structures And Characterization Of The Complexes With 3-Phenyl-4-methyl-5-pyridyl-1,2,4-triazoles

1,2,4-Triazoles and their derivatives are widely used in many fields.In order to study of the complexes of 1,2,4-triazoles,we have synthesized some 1,2,4-triazole compounds and transition-metal complexes.This thesis is composed of following sections:1.Four compounds of 1,2,4-triazoles have been synthesized.The single crystal structure of 3-phenyl-4-methyl-5-(2-pyridyl)-1,2,4-triazole was determined by X-ray analysis.2.Six transition-metal complexes of[CuL2(H2O)2](ClO4)2,[NiL2(H2O)2](NO3)2,[CdL2(N03)2]·CH3CN,[CoL2(CH3OH)2](C104)2,[ZnL2(C2H5OH](C104)2 and[CuL2C1]C1-H2O were prepared from 3-phenyl-4-methyl-5-(2-pyridyl)-1,2,4-triazole(L),and their single crystal structures were determined by X-ray analysis.The central Cu(II)atoms of[CuL2C1]Cl-H2O have distorted tetragonal-pyramidal geometries with CuN4Cl.3.The complexes of[CuL2(H2O)2](ClO4)2,[NiL2(H2O)2](NO3)2,[CuL2Cl]Cl·H2O and[CdL2(NO3)2]·CH3CN have been characterized by IR,UV,fluorescence properties,XRD and TGA.
