The crystal structure of erbium (Ⅲ) complex of benzene acetic acid is reported. The complex crystallizes in the monoclinic space group P_2_1/a with a=0.9008(3) nm, b=1.4242(5) nm, c=1.8437(7) nm; β=98.80(3)°, V=2.337(1) nm~3, Z=4. The mechanism of thermal decomposition of complex has been studied by TG-DTG-DTA. The activation energy for dehydration reaction has been calculated by Freeman-Carroll method. The enthalpy change for dehydration and phase change process has been determined.
