Abstract
A novel 3D Zn(II) complex [Zn(H2hmIDC)]n (1) has been synthesized through the reaction of an achiral ligand 2-(hydroxymethyl)-1H-imidazole-4,5-dicarboxylic acid (H4hmIDC) with Zn(NO3)2. Single crystal X-ray diffraction determination shows that complex 1 is the first 3D framework based on left and right-handed helical chains, in which all of the H2hmIDC2− ligands coordinate to Zn(II) ions with μ3-bridging mode. The overall structure of complex 1 can be described as a (3,3)-connected topology with the topological notation of {82·10}2. The TG analysis shows that it possesses great thermal stability. In addition, its IR spectra, PXRD pattern and fluorescence property have been investigated.
