摘要
The self-assembly of Co（OAc）·4H2O with H2tbip and bipy （H2tbip = 5-tert-butyl isophthalic acid, bipy = 4,4＇-bipyridine） generates one new complex, [Co3（tbip）2（Htbip）2（bipy）]n, which has been characterized by elemental analysis, X-ray diffraction, and IR spectroscopy. Single-crystal X-ray analysis reveals that it crystallizes in the triclinic space group P1 with a = 9.471（6）, b = 12.597（8）, c = 12.899（8）, α = 84.660（7）, β = 70.548（7）, γ = 81.965（7）o, V = 1435.1（15）3, Mr = 1215.85, Dc = 1.407 g/cm3, Z = 1, F（000） = 629, μ（MoKα） = 0.926 mm-1, the final R = 0.0623 and wR = 0.1724. The complex consists of a tbip bridged trinuclear cobalt（） unit and is further linked by 4,4＇-bipyridine molecule to form a 2D supramolecular network.
