NbFeTe{sub 2} is a layered cluster compound in which intra Fe{endash}Fe bond distance is 2.488 {Angstrom}. The magnetic susceptibilities between 100 and 300 K are fit to Curie{endash}Weiss law with C=1.29 emuK/mol, and {theta}=+69.2 K. The effective magnetic moment of 3.67 {mu}{sub B} per Fe at 300 K corresponding to three unpaired electrons may suggest the formation of Fe{endash}Fe single bond. M{umlt o}ssbauer spectrum at 77 K shows a paramagnetic doublet with {delta}=0.36 mm/s and {Delta}E=0.62 mm/s. The {chi}{sub ac} measurement reveals the occurrence of a spin glass transition at T{sub f}=44.0 K. The irreversibility of magnetic properties below T{sub f} has been studied with the measurements of the dc susceptibility, remanent magnetization, and hysteresis loop for both zero field cooled and field cooled samples. The competition between antiferromagnetic and ferromagnetic interactions probably cause the spin glass behavior. {copyright} {ital 1997 American Institute of Physics.}
