Synthesis, Crystal Structure and Properties of a New Cadmium Compound with (1,1'-(1,4-Butanediyl)bis(imidazole) and p-Hydroxybenzoic Acid

摘要

A new metal-organic framework based on bbi and PHBA (bbi =1,1'-(1,4-butanediyl)bis(imidazole),PH-BA =p-hydroxybenzoic acid),namely,[Cd(bbi)(PHBA)2]n (1) has been synthesized by the conventional method.Compound 1 displays a two-dimensional (2D) layer structure possessing the left-and right-handed helical chains and stabilized by intermolecular hydrogen-bonding to form a three-dimensional (3D) supramolecular structure.Topologically,the 2D layer belongs to well-known (4,4) network topology.The structure has been determined by single-crystal X-ray diffraction analyses,and further characterized by infrared spectra (IR),elemental analyses and powder X-ray diffraction.In addition,the thermal behavior and luminescent properties of [Cd(bbi)(PH-BA)2]n have been investigated in detail.
