Static and dynamic electric quadrupole interactions of ^{111}Cd in complexes with diethylenetriaminepentaacetic acid were studied by the time differential perturbed angular γγ-correlation technique using two parent isotopes, ^{111}In(EC)^{111}Cd and ^{111 m}Cd. The measurements were carried out using neutral aqueous solutions of the diethylenetriaminepentaacetic- acid-complexes with initial isotopes at 293 K and 77 K. It was shown that the ^{111}Cd-diethylenetriaminepentaacetic-acid-complex in aqueous solutions at pH = 7.0 is characterised by the re-orientational correlation time of 7.7×10^{-11} s and an electric field gradient V_{zz}=6.7(2)×10^{21} V/m^2 with an asymmetry parameter η=0.75(5). A direct comparison of the electric quadrupole interaction parameters for diethylenetriaminepentaacetic- acid-complexes with ^{111}In and ^{111m}Cd confirmed the proposal about the fragmentation of the complexes caused by the after-effects of electron capture in ^{111}In. An observed difference in the electric quadrupole interaction parameters obtained for the solutions with ^{111}In and ^{111m}Cd complexes reflects a process of a chemical rearrangement of the complex structure after the In decay into Cd
