Abstract
A novel coordination polymer [(DDTD)(Cu3I5)]n(DDTD = 5, 8-diazoniadispiro[4.2.4.2]tetradecane dication) was obtained and characterized by X-ray crystallography, elemental analyses, and IR spectroscopy. In the polymer, a unique 1D helical chain of (Cu3I5)n cluster was constructed, and the C-H· · ·I intermolecular interactions extended the 1D entities into high-dimensional frameworks to stabilize the supramolecular architecture. Furthermore, thermal property (TG, DTG and DSA) of the polymer was studied.
