摘要：

A novel 3D metal-organic framework of zinc(II) imidazole-4,5-dicarboxylate, [Zn-5(L)(2)(HL)(2)(DMF)(4)](n) (H3L = 4,5-imidazoledicarboxylic acid), was solvothermally synthesized and structurally characterized by single-crystal X-ray diffraction. This compound crystallizes in the orthorhombic system with the space group Pbca and cell parameters a = 14.1613(8) angstrom, b = 15.6764(9) angstrom, c = 16.1345(9), V= 3581.8(4) angstrom(3) and Z = 4. The crystal structure presents a novel 3D framework with the rare four-fold helical structure and open channels, exhibiting guest-co ordination sites at channel walls and strong fluorescent emission.
