The title compound {[Cu4(OH)4(2,2’-bpy)4(bqdc)]·2ClO4}n 1 (bqdc = 2,2’-biquino- line-4,4’-dicarboxylic acid) has been synthesized by hydrothermal method. Its crystal structure is of triclinic, space group P1 with a = 7.6561(5), b = 12.4652(8), c = 15.7501(10) , α = 80.0480(10), β = 87.7900(10), γ = 74.0800(1)o, V = 1423.65(16) 3, Z = 2, C30H23ClN5O8Cu2, Mr = 744.06, Dc = 1.736 g/cm3, μ = 1.651 mm─1, F(000) = 754, the final R = 0.0421 and wR = 0.1163 for 4973 observed reflections with I > 2σ(I). In 1, tetra-copper chair-like clusters of [Cu4(OH)4(2,2’-bpy)4]4+ are connected by bqdc ligands to form one-dimensional chains, which are further connected by hydrogen bonds to generate a two-dimensional supramolecular network .
