A new coordination polymer,[Cu2(bptc)(2,2'-bpy)2(H2O)]H2O(2,2'-bpy=2,2'-bipyridine,H4bptc=biphenyl-2,5,2',5'-tetracarboxylic acid),has been synthesized under hydrotherreal conditions. The structure was characterized by single-crystal X-ray diffraction, elemental analysis, IR spectra and thermogravimetric analysis. It crystallizes in triclinic, space group P1 with a=10.6447(12),b=11.0191(12),c=16.1253(18)A,α=79.538(2),β=88.0720(10),γ=61.6650(10)°,V=1634.1(3)A3,C36H26Cu2N4O10,Mr=801.69,Z=2,Dc=1.629 g/cm3,μ(MoKa)=1.370 mm-1,F(000)=816.0,R=0.0418 and wR=0.1135 for 4416 observed reflections with I＞2σ(I).X-ray analysis shows that the title complex exhibits 1D wavelike [Cu2(bptc)]n chains with two types of diamond-shaped pores.These 1D chains are linked into a 3D supramolecular structure via O-H…O,C-H…O interactions and weak π…π stacking interactions. There exist H-bonded helices in a right-and left-handed sequence by turns in a 2D layer. Moreover, thermal stability has been studied and magnetic measurements show antiferromagnetic interactions for this complex.
