Solvothermal Synthesis and Characterization of An Organic Ligands Bridging Zinc Complex with Porous Structure

A new two dimensional zinc complex was reported. This compound was synthesized under solvothermal condition by using THF as solvent. The crystal structure was determined by using single crystal X-ray diffraction. Crystal data: Zr', (B DC)( D ABCO)( H 20)z, monoclinic, space group C 2/c,a =10.871(17)，b=19.10 (3)，c=7.15 5(川，a= 90,口二115.99(3)，Y=90,Z 二8,V 二1335(4)，Dr二2.085岁cm3，R二0.08 58. This compound has two-dimensional network structure. Each zinc metal center was coordinated by two DABCO, two BDC and one water molecule. DABCO and BDC ligands bridge to two zinc atoms, respectively. The extension of this〔。-ordination result in a two-dimensional network and form a 7.16 x 9.98A zporous structure. It was interesting to find that the 2-dimensional was an interpenetrated structure formed by two coordinate polymer networks. This kind of structure is very rare in the coordinate compounds. The m-m interaction between the phenyl group of BDC was believed to the key of the growth of this coordination network.
