“…PrT 2 X 20 crystallize with the cubic CeCr 2 Al 20 -type structure (space group Fd3 ̅ m) [5]. The crystalline electric field (CEF) ground state of the Pr ion in these compounds is the non-Kramers  3 doublet [6][7][8][9], which carries no magnetic dipole but electric quadrupoles and a magnetic octupole. Among PrT 2 X 20 , PrT 2 Zn 20 (T = Ir and Rh) and PrT 2 Al 20 (T = Ti and V) have been intensively studied because they exhibit superconducting transitions in the presence of the quadrupolar ordering [1][2][3][4].…”

We have grown a new Pr-based compound PrRu 2 In 2 Zn 18 and have studied its structural and magnetic properties by single-crystal X-ray diffraction and magnetization measurements, respectively. The single-crystal X-ray analysis showed that this compound is a quaternary derivative of the cubic CeCr 2 Al 20-type. Magnetic susceptibility  obeys the Curie-Weiss law above 50 K. The effective magnetic moment,  eff = 3.58  B /Pr, agrees with the value expected for a free Pr 3+ ion. Below 10 K, Van-Vleck paramagnetic behavior is observed, indicating that the crystalline electronic field ground state of the Pr 3+ ion is nonmagnetic.
