报道了具有CeCr2Al20结构的化合物LnTi2Al20(Ln=La-Pr，Sm，Yb)、LnV2Al20(Ln=La-Pr，Sm)和LnCr2Al20(Ln=La-Pr，Sm，Yb)的晶体生长和全结构测定。比较了熔剂生长的非磁性化合物CeM2Al20(Ln=Ce，Yb；M=Ti，V)与PrCr2Al20单晶的电阻率、磁化率和热容。特别令人感兴趣的是PrCr2Al20，它没有显示出向测量的最低温度(电阻率测量为400mK，磁化率测量为1.8K)的任何相变，并在低温下表现出近藤行为。
Crystal growth and full structure determination of compounds adopting the CeCr2Al20structure type, LnTi2Al20(Ln=La–Pr, Sm, and Yb), LnV2Al20(Ln=La–Pr, and Sm), and LnCr2Al20(Ln=La–Pr, Sm, and Yb), are reported. Resistivity, magnetic susceptibility, and heat capacity of flux grown single crystals of the nonmagnetic CeM2Al20(Ln=Ce, Yb; M=Ti, V) compounds are compared to PrCr2Al20. Of particular interest is PrCr2Al20which does not show any phase transition down to the lowest temperature of the measurement (400mK in resistivity measurement and 1.8K for magnetic susceptibility measurements) and exhibits Kondo behavior at low temperatures.
