摘要: Two 4,5-dichlorophthalate-based metal complexes, {[Cu(bipy)(dcpa)]·H₂O}_n (1) and {[Cu₂(bipy)₂(Hdcpa)₃]·H₂O·C₂H₅OH·Hdcpa} (2, H₂dcpa=4,5-dichlorophthalic acid and bipy=2,2'-bipyridine), were synthesized and characterized structurally and magnetically. Complex 1 is of orthorhombic system, space group Fdd2 with a=20.5821(8), b=20.9013(12), c=17.0270(7) Å, V=7324.9(6) ų, D_c=1.707 g/cm³, M_r=470.74, Z=16, F(000)=3792, μ=1.519 mm^-1, the final R=0.0223 and wR=0.0549 for 9239 observed reflections with I>2σ(I). Complex 2 crystallizes in triclinic, space group P1 with a=14.1439(12), b=14.2981(12), c=15.1054(14) Å, α=72.121(2), β=77.703(2), γ=81.829(2)°, V=2830.9(4) ų, D_c=1.689 g/cm³, M_r=1439.55, Z=2, F(000)=1452, μ=1.207 mm^-1, the final R=0.0536 and wR=0.0981 for 16422 observed reflections with I>2σ(I). Complex 1 exhibits a diamond-like framework with centrosymmetric binuclear subunits extended by pairs of doubly deprotonated dcpa^2- linkers. By contrast, 2 is an asymmetric binuclear entity bridged by carboxylate group of mono deprotonated Hdcpa^- ligands. Weak anti- and ferromagnetic interactions are respectively mediated in the carboxylate aggregated binuclear subunits of 1 and 2.
