Abstract High quality single crystal sample of layered transitional metal bismuthide BaAg_2-δBi₂ was prepared by self-fluxing method. The crystal structure,chemical composition,electrical and magnetic properties of high quality single crystal sample were systematically studied by many kinds of experimental methods. The experiment results indicate that the compound BaAg_2-δBi₂ is a layered transitional metal compounds with AgBi₄ and BiAg₄ tetrahedral layers, which is different from that there is only one kind of FeAs₄/FeSe₄ tetrahedral layers in iron-based superconductor. The variation of resistivity and magnetic susceptibility as a function of temperature shows that BaAg_2-δBi₂ presents a good metal behavior and paramagnetism in the temperature ranges of 1.8 — 300 K,and the paramagnetism mainly originate from conduction electrons.
