Using the heavy rare-earth complex anions,[Ln (NCS) 6] 3-(Ln= Ho, Er, Yb and Y), we have synthesized three series of metallic compounds,(BO) x [Ln (NCS) 6],(TTP) x [Ln (NCS) 6](x≈ 8) and (DIEDO) 6 [Ln (NCS) 6]. The BO and TTP salts are metallic down to very low temperature, while the resistivity of the DIEDO salts increases below about 40 K. These are the first examples of stable metals based on organic π-donors and rare-earth 4f ions.
