摘 要: | The title compound, Co(C_(16)H_(10)N_2S_4)_2(H_2O)_4](C_(14)H_9N_2O_4)2(1,C_(16)H_(10)N_2S_4=4-pyridine-tetrathiafulvalene-4-pyridine and C14 H9 N2 O4 = 4-(4-carboxyphenyl)diazenyl)benzoate),has been successfully synthesized under hydrothermal conditions. The structure was determined by elemental analyses and single-crystal X-ray diffraction analysis. Moreover, the conductivity property of compound 1 was investigated. Compound 1 crystallizes in triclinic system, space group P1 with a = 6.4006(3), b = 7.1818(4), c = 33.0932(14) ?, α = 89.261(4), β = 86.530(3), γ = 66.642(4)°, V =1393.90(12) ?3, Z = 1, C60 H46 N8 O12 S8 Co, M3 r = 1386.46, Dc = 1.652 g/cm, μ = 0.684 mm-1 and F(000) = 713. The final R = 0.0411 and wR = 0.0810 for 3936 observed reflections with I 2σ(I).Compound 1 contains one-half of the complex cation with the CoI I ion located on an inversion center,and one 4-(4-carboxyphenyl)diazenyl)benzoate counter anion. The Co atom has a N2 O4 octahedral coordination. Complex 1 forms a three-dimensional supramolecular network and a semiconducting behavior is observed with srt= 0.04 S·cm-1.
