Single‐component molecular conductors [M(tmstfdt) 2 ] (M = Ni, Au; tmstfdt = trimethylenediselenadithiafulvalenedithiolate) substituted with Se atoms are prepared and found to be isostructural with [M(tmdt) 2 ] (M = Ni, Au; tmdt = trimethylenetetrathiafulvalenedithiolate). Measurements of the electrical conductivity and magnetic susceptibility of [Ni(tmstfdt) 2 ] show that it has essentially metallic properties down to low temperatures. The resistivity measurements of [Au(tmstfdt) 2 ] suggest it undergoes a metal‐insulator phase transition at around 100 K. Magnetic susceptibility and ESR measurements of [Au(tmstfdt) 2 ] indicate that it undergoes a magnetic transition at around 5 K, which is much lower than theantiferromagnetic (AF) phase‐transition temperature of [Au(tmdt) 2 ] (110 K).
