摘要

Attempts to create metal-or ganic frameworks(MOFs)with zeolitic topologies,metal(zinc(II)and cobalt-(II))imidazolates have repeatedly been used as the metal-organic motifs of in organic silicate analogues.By modulat ing the synthetic strategy based on the solvothermal and liquid diffusion method,seven further MOFs(includ ing at least three zeolitic MOFs)of zinc(II)imidazolates.[Zn(im)2·xG](G=guest molecule,x=0.2-1)1a-7a,have been successfully synthesized.Of these,1a-3a are isostructural with the previously reported cobalt analogues 1b-3b,respectively,while 4a-7a are new members of the metal imidazolate MOF family.Complex 4a exhibits a structure related to silicate CaAl2Si2O8 of CrB4 topology,but with a higher network symmetry;complex 5a has a structure with zeolitic DFT topology that was discovered in zeolite-related materials of DAF-2,UCSB-3.and UCSB-3GaGe;complex 6a demon strates an unprecedented zeolite-like topology with one dimensional chan nels with 10-rings;and 7a displays a structure of natural zeolite GIS(gis-mondine)topology.All of these poly morphous MOFs were created only by using certain solvents as structure-di recting agents(SDAs).Further exten sive metal-organic frameworks with zeolitic topologies can be envisaged if other solvents were to be used.
