Thermochemistry of copper complex of 6-benzylaminopurine

摘要

The copper(II) complex of 6-benzylaminopurine (6-BAP) has been prepared with dihydrated cupric chloride and 6-benzylaminopurine. Infrared spectrum and thermal stabilities of the solid complex have been discussed. The constant-volume combustion energy, Delta U-c, has been determined as -12566.92 +/- 6.44 kJ mol(-1) by a precise rotating-bomb calorimeter at 298.15 K. From the results and other auxiliary quantities, the standard molar enthalpy of combustion, Delta H-c(m)theta and the standard molar of formation of the complex, Delta H-f(m)theta were calculated as -12558.24 +/- 6.44 and -842.50 +/- 6.47 kJ mol(-1), respectively.
