| Abstract: | A terephthalato-bridged copper(II) complex [Cu2(tpt)(bpy)2(H2O)4][Cu2(tpt)3(bpy)2 (H2O)2] (1) (tpt = terephthalate, bpy =; 2,2'-bipyridine) was synthesized by the reaction of Cu(ClO4)2  6H2O and terephthalic acid in the presence of 2,2'-bipyridine in H2O solution. Crystal structure of 1 was determined by X-ray diffraction analysis in the triclinic space group P , with a = 10.7327(10) Å, b = 11.1658(11) Å, c = 17.3768(16) Å,  = 108.063(2) ,  = 91.064(2),  = 116.721(2), V = 1737.5(3) Å3, and Z = 2. Both the anion and the countercation in 1 are copper(II) complexes linked by terephthalate bridges in the bis(monodentate) (syn–anti) mode. The anion and the countercation are also linked by two hydrogen bonds between coordinating water molecules and terephthalate ligand. |
