Abstract: The title compound [Zn3(BTC)2(H2O)3]n (BTC=1,3,5-benzenetricarboxylic acid) was synthesized under mild conditions and its crystal structure was determined by single crystal X-ray diffraction. The compound crystallizes in the cubic system and belongs to space group Fm-3m with a=2.662 6(3) nm ,V=18.877(4) nm3,Z=16,Dc=1.51 g/cm3,Mr=664.4,μ=0.198 mm-1 , F(000)=852 ,R=0.062 5,wR=0.129 4. Its structure reveals that the title polymer is composed of dimeric zinc tetracarboxylate units,with a short Zn-Zn internuclear separation of 0.295 0(4) nm. The coordination of BTC ligands with Zn ions forms a 3D infinite framework with about 1.117 4 nm×1.327 4 nm pores along the [001],[100] and [010] direction.
