[Cu(C8H4F3O2S)2(C3H7NO)], Mr = 579. 0, monoclinic, P21/c, a = 9. 4851(6), b = 26. 6574(6), c=9.2619(6) A ,β=96.08(3)°, V = 2328.7A3, Z=4, Dc=1. 65gcm-3, μ(MoKa) = 7. 2cm-1, F (000) = 1172, MoKa radiation, final R = 0. 074 and Rw = 0. 068 for 1841 reflections with I≥3σ(Ⅰ). The Cu(Ⅱ) atom is coordinated by five oxygen atoms, one of which from DMF is in the axial position, to form a square pyramidal geometry. That the thenoyl groups in the ligands take the cis-form around the Cu(Ⅱ) atom is explained by the hydrogen bonding effect.
