The results of electrical resistance (1.4 - 300 K), magnetization (2-300 K) and heat-capacity (2 - 50 K) measurements in Y2PdGe3, found to crystallize in a AlB2-derived hexagonalstructure, are reported. The results establish that this compound is superconducting below 3 K. This obervation is interesting considering that this compound is the first superconductor among the ternary members derived from the hexagonal AlB2 structure. With superconductivity being uncommon even among binary alloys derived from AlB2 structure and with recent excitement on the observation of high temperature superconductivity in MgB2, this finding gains importance.
