Abstract
A novel complex, bis( trans-bis( N, N-dimethyl-(1-( R)-phenyl-2-( S)-methyl-2-aminoethoxy-N,O))-copper(II)) heptahydrate (abbreviated as Cu 2(C 11H 16NO) 4·7H 2O(cr)), was synthesized by the method of liquid phase reflux. The composition and structure of the complex were characterized by chemical analysis, elemental analysis, FTIR, and X-ray crystallography. A reasonable thermochemical cycle was designed based on the preparation reaction of the coordination compound, and standard molar enthalpies of dissolution of reactants and products were measured by an isoperibol solution-reaction calorimeter. Finally, the standard molar enthalpy of formation of the complex Cu 2(C 11H 16NO) 4·7H 2O(cr) was determined to be −(4525.22 ± 13.71) kJ · mol −1 in accordance with Hess’s law.
