摘要：

A copper(II) complex, [Cu4L4(H2O)(9)]center dot 10H(2)O (1), (H2L=2,2'-dimethoxy-4,4'-biphenyldicarboxylic acid), was synthesized and characterized by FT-IR, TGA, powder and single crystal XRD. The complex crystallizes in orthorhombic system with space group Pnma, a=1.493 9(3) nm, b=3.051 6(6) nm, c=1.569 4(3) nm, V=7.154(2)' nm(3), Z=4 with final R=0.040 6. The complex contains four crystallographically distinct Cu(II) ions and each Cu(II) ions locates in a square-pyramid environment. Three mu(2)-bridging water molecules connect the four Cu(II) ions to form a short zigzag chain which is further joined by the L ligands to generate a 2D layer. A lot of hydrogen bonds assemble the 2D layer into a 3D supramolecular structure. The TG analysis shows that the complex is stable below 295 degrees C. Magnetic susceptibility measurement indicates that there is a weak antiferromagnetic exchange coupling between the Cu(II) ions. CCDC: 872818, 1.
