Abstract Single crystals of the new molecular metal (Per) 2 Au(i-mns) 2 were obtained by electrocrystallization. The electrical conductivity is ≈300 S/cm at 300 K and presents a broad maximum at ca. 50K. The thermoelectric power, S RT ≈36 μ V/K, decreases almost linearly with temperature upon cooling down to 115 K, confirming the metallic properties at high temperature. The EPR signal consists on a single line ( Δ H pp ≈1G and g≈2.004 at 300K) ascribed to the delocalized electrons in the perylene chains, in agreement with the Pauli-like behaviour of the static magnetic susceptibility ( χ p ≈2.4×10 −4 emu/mol).
