Two Interpenetrated Dia-type Coordination Polymers Constructed from Mixed Dicarboxylate and Bis(imidazol)-based Ligands

摘要

Two novel interpenetrating diamond frameworks,namely [Cd(mal)(bix)]n(1) and {[Zn(sub)(bib)]n·H2O}n(2)(H2mal=maleic acid,H2 sub=suberic acid,bix=1,4-bis(imidazol-1-ylmethyl)-benzene,bib=1,4-bis(N-imidazolyl)butane) were hydrothermally synthesized and characterized by elemental analysis,infrared spectra(IR),and single-crystal X-ray diffraction.Single-crystal X-ray diffraction analysis reveals that compound 1 crystallizes in the orthorhombic system with space group Pnma and features a 3-fold interpenetrating diamond framework.Compound 2 exhibits a 4-fold interpenetrating diamond network.The luminescent properties of these two compounds have also been investigated in detail.
