We present the results of thermodynamic and optical spectroscopy measurements of the Pr_3CrGe_3Be_2O_(14) compound - a member of the recently discovered Be-subgroup of the langasite family. Despite the presence of both rare-earth and transition-metal subsystems in Pr_3CrGe_3Be_2O_(14), no long-range magnetic order has been found down to 0.4 K in terms of both magnetization M and specific heat C_p. These data are compared with those on Pr_3AlGe_3Be_2O_(14). Both compounds evidence the Schottky anomaly at low temperatures, most pronounced in the case of Pr_3CrGe_3Be_2O_(14).
