Synthesis, Characterization, Function And Thermochemistry On The Copper Complexes And Functions Of 6-benzylaminopurine

The copper complexes have been synthesized with 6-benzylaminopurine and dihydrated cupric chloride. Reaction conditions and influencing factors for preparations of complexes were discussed and their properties were characterized. Thermochemical characteristics for the complex were discussed in this paper. In addition, Trace elements supplements and antibacterial and antivirus on growth of pipless grapes were studied.All complexes were identified as the chemical compositions by chemical and elemental analyses primarily. IR spectra of the complexes showed that 6-benzylaminopurine was coordinated to cupric ion through the nitrogen atom in the ligand. UV spectrum showed charge transfer between cupric ion and ligand is a process. FS spectrum of the complexes indicated that features of spectra were not remarkable, only its intensity change. Electrochemical behaviours of complexes on the platinum electrode were researched with cyclic voltammetry. It is indicated that the electrochemical process of the complexes was a quasi-reversible process.The decomposition of the complexes was studies by TG-DTG technique. The results showed that the complexes were not stable above corresponding some degree. Their decomposition mechanisms were predicted, and the decomposition of complexes were speculated on several stages, The final products of oxide were obtained by completely decomposed.The constant-volume combustion energies,â–³_cU, for the solid complexes were determined by RBC-â…¡type precision rotating-bomb calorimeter at 298.15K. The standard molar enthalpies of combustion,â–³_cH_m^θ, and standard molar enthalpies of formation,â–³_cH_m^θ, were calculated for these complexes, respectively. The results are as follow:1. ([Cu(C₁₂H₁₂N₅)₂Cl₃]Cl·2H₂O):â–³_cU=-12566.92±6.44kJ·mol^-1,â–³_cH_m^θ=-12558.24±6.44kJ·mol^-1,â–³_fH_m^θ=-842.50±6.47kJ·mol^-1.2. ([Cu(C₁₂H₁₂N₅)₂Br₃]Br·2H₂O):â–³_cU=-12503.71±5.58kJ·mol^-1,â–³_cH_m^θ=-12495.03±5.58kJ·mol^-1,â–³_fH_m^θ=-681.99±5.63kJ·mol^-1.From the monocrystal structure of the complex (Chlorine), the crystal system of the complex was determined as momoclinic system, space group P2(1)/c,a=10.719(2)A, b=21.235(4)A, c=13.573(3)A,α=γ=90°,β=110.66(3)°,V=2890.9(10)A³, Dc=1.594Mg/m³, Z=4, F(000)=1420,μ=1.169mm^-1. Other coordination patterns and possible crystal structures of the complex with 6-benzylaminopurine were primarily discussed according to the known crystal structure of complex.
