We report temperature dependent ac susceptibility (χ) measurements on a high quality single crystal of Tb2PdSi3, crystallizing in a AlB2-derived hexagonal structure. This compound is found to exhibit features attributable to quasi-low-dimensional magnetism at high temperatures and \it anisotropic spin-glass-like behavior at low temperatures (< 10 K) with an unusually large frequency dependence of peak temperature in ac χ(T). This compound thus presents a novel situation in \it metallic magnetism, considering that the former phenomenon is normally encountered only among insulators, whereas the anisotropic spin-glass-like behavior, to our knowledge, has not been known in stoichiometric intermetallic compounds.
