摘　　要：在有机溶剂THF中 ,合成了一个新颖的、以对苯二甲酸 (BDC)和三乙烯二胺为桥联配体、具有二维骨架结构的金属有机微孔配合物Zn2 (BDC) (DABCO) (H2 O) 2 ,并对其进行了单晶结构解析 ,证实该晶体结构属单斜晶系 ,空间群C2 /c ,a =10 .871(17) ,b =19.10 (3) ,c=7.15 5 (11) ,α=90 ,β =115 .99(3) ,γ =90 ,Z =8,V =1335 (4 ) ,Dc=2 .0 85 g/cm3 ,R =0 .0 85 8.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: Zn-2(BDC) (DABCO) (H2O)(2), monoclinic, space group C2/c, a = 10.871(17), b = 19.10(3), c = 7.155(11), alpha = 90, beta = 115. 99(3), gamma = 90, Z =8, V = 1335(4), Dc =2.085 g/cm(3), R = 0. 0858. 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 coordination result in a two-dimensional network and form a 7.16 x 9.98Angstrom(2) porous 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 pi - pi interaction between the phenyl group of BDC was believed to the key of the growth of this coordination network.
