Perturbed γ-γ angular correlation spectroscopy was applied to study hyperfine interaction parameters for ^{111}In probes in intermetallic compounds of D8_{2} structure. The perturbed γ-γ angular correlation spectra measured in Ag_{5}Zn_{8} and Ag_{5}Cd_{8} phases reflect a number, population and symmetry of nonequivalent substitutional sites occupied by the indium probes. The temperature dependences of the observed electric field gradients were measured in the temperature range 37-500 K
