Synthesis and Crystal Structure of the Porous Metal—Organic Coordination Polymer [Zn4(Ndc)4(Oxdz)2] · 2H2O

摘要

New metal—organic coordination polymer [Zn4(Ndc)4(Oxdz)2] · 2H2O (H2Ndc = 2,6-naphtha-lehedicarboxylic acid, Oxdz = 1,3,4-oxadiazole) was prepared by heating a solution of zinc nitrate, naphtha-lenedicarboxylic acid, and 4-aminotriazole in DME Of particular interest is the in situ transformation of 4-aminotriazole into 1,3,4-oxadiazole. The structure and the composition of the obtained compounds were established by X-ray diffraction, IR spectroscopy, and elemental analysis. The metal—organic framework is electrically neutral and forms a channel structure with the pore diameter of 9 A.
