The electric field gradients (EFG), V zz and V xx − V yy , at the Sb site exhibit unusual temperature dependence below 30 K. To explain these features, we discuss the coupling between the Sb nuclear quadrupole moment and Pr 4f 2 -derived multipole moments. The observed T dependence of EFG is well explained by the CEF quasi-quartet consisted of Γ 1 singlet and Γ
