    “…[Image: see text] Two coordination complexes have been made by combining the dithiolene complexes [M(mnt)(2)](2–) (mnt = maleonitriledithiolate; M = Ni(2+) or Cu(2+)) as anion, with the copper(II) coordination complex [Cu(Stetra)] (Stetra = 6,6′-bis(4,5-dihydrothiazol-2-yl)-2,2′-bipyri-dine) as cation. The variation of the metal centers leads to a dramatic change in the conductivity of the materials, with the M = Cu(2+) variant (Cu–Cu) displaying semiconductor behavior with a conductivity of approximately 2.5 × 10(–8) S cm(–1), while the M = Ni(2+) variant (Ni–Cu) displayed no observable conductivity. …”

    “…Thus, if the experimental system is exposed to air, the low quantities of O(2) molecules present should result in the oxidation of the metallic atoms. Furthermore, the O(2) molecules adsorbed on WS(2)-Au(2S2) and WS(2)-Cu(S) introduced a half-metallic behavior, making the system suitable for applications in spintronics.…”
