摘要
kappa-Di[3,4;3',4'-bis(ethylenedithio)-2,2',5,5'-tetrathiafulvalenium] bromo(dicyanamido)-cuprate(I) (2/1), C22H16BrCuN3S16, M(r) = 978.8, orthorhombic, Pnma, a = 12.871 (5), b = 29.548 (9), c = 8.466 (6) angstrom, V = 3220 (3) angstrom3, Z = 4, D(x) = 2.019 Mg m-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 2.93 mm-1, F(000) = 1956, T = 20 (1) K, final R = 0.049 for 2400 independent observed reflections with F(o) > 3-sigma(F(o)). The structure contains molecular dimers of partially charged BEDT-TTF dagger radical cations. The dimers are arranged orthogonal to neighboring dimers and form conducting layers, separated by anion layers consisting of parallel, infinite zigzag ...dicyanamido-Cu(Br)-dicyanamido...chains.
