In an attempt to synthesize supra-molecular complex of copper (II) with mixed ligands in a solution reaction of Cu(ClO4)2· 6H2O with 4,5-diazafluorene-9-one (dafo) and o-phthalic add, the bright blue column-like crystal [Cu(dafo)2(H2O)2]-(ClO4)2 was obtained. Its structure was determined by single-crystal X-ray diffraction study. The crystal belongs to monoclinic system, space group P2(1)/n with cell dimensions: a = 0.7547(3) nm, b = 1.2021(5) nm, c = 1.3190(5) nm, α = 90.000(5)°, β = 90.000(5)°, γ = 90.000(5)°, V = 1.2600(9) nm3, Z = 2, F(000)=670, Mr = 662.83, Dc = 1.747 g/cm3, μ (Mo Kα) = 1.154 mm−1, R1, = 0.0455, wR2 = 0.1041. The analysis of the crystal structure indicates that the complex has a two-dimensional network structure which is formed by hydrogen bonds. |
