(DMF) (1) and Co2 (BDC) 2 (C5H5N) 4 · 2 (DMF) were synthesized under moderate conditions with two-dimensional layered network structure. (C5H5N) (2), and its structure was characterized by ICP and X-ray single crystal diffraction analysis.1 The cell data of C14 H14 N3 O5Zn, Mr = 3 69 65, monoclinic system, C2 / c space group, cell parameters a = 2 10 5 9 (4) nm, b = 1 0 3 16 (2) nm, c = 1 483 6 (3) nm, β = 99 0 9 = 3 182 6 (11) nm3, Z = 4, DX = 1543 Mg / m3, μ = 1571 mm-1, F (0 0 0) = 15 12. The final consistency factor is R = 0 0 697 , The cell data of Rw = 0 2 0 18.2: C47H47N7O10Co2, Mr = 98778, monoclinic, P2 (1) / n space group with unit cell parameters a = 1 0 82 9 (2) nm, b = 1 5 43 1 3 nm, c = 1 44 2 8 nm, β = 10 1 65 (3) °, V = 2 3 612 (8) nm3, Z = m3, μ = 0 767mm-1, F (0 0 0) = 10 2 4. The final concordance factors are R = 0 0 65 2, Rw = 0 1888.1 and 2 are all composed of inorganic clusters M2 (CO2) 4 (M = Zn, Co) formed by the connection of the benzene ring network structure, they are present by the four inorganic clusters and four benzene rings form a ring, the size of about 0. 9nm 0 9nm. Since imidazole, and pyridine, respectively with 1 and 2 the poles of the inorganic ligand clusters, which prevents formation of three-dimensional framework structure
