Beschreibungen/Notizen

• [C NiO [C , M = 498.09 is triclinic, P1̄, a = 3.7718(6), b = 7.436(2), c = 17.511(4) Å, α = 88.67(2), β = 86.93(2), γ = 85.05(2)°, V = 488.51 Å , Z = 1, d = 1.69 gcm , final R = 0.035 for 1454 observed independent reflections. The crystals consist of segregated regular parallel stacks of planar metal complex cations and tenq counterions with intermolecular H bonds stabilizing the structure. The compound is metallic at room temperature. A metal to semiconductor transition around 230 K shows up in thermopower data, in the microwave conduc­tivity and epr around 170 K. It is not visible in the static magnetic susceptibility.
