Syntheses and crystal structures of three supramolecular halides: (DDTD)[Zn(N_3)_3Cl], (DDTD)[Hg_2Br_6], (DDTD)[Cd_4(N_3)_6(Cl)_8] directed by DDTD dication

摘要

The self-assembly reaction ofmetal halides with DDTD dication (DDTD = 5,8 -Diazoniadispiro[4.2.4.2] tetradecane) yielded three novel organic-inorganic hybrid mental halides (DDTD)[Zn(N_3)_3Cl] (1), (DDTD)[Hg_2Br_6] (2), and (DDTD)[Cd_4(N_3)_6(Cl)_8] (3), which are characterized by X-ray crystallography and IR spectroscopy. The crystal structures of 1-3 show that they all crystallize in monoclinic systems. Compound 1 is mononuclear complex, compound 2 is binuclear complex, and compound 3 is a tetranuclear polymer. These compounds contained a variety of inorganic frameworks, due to the different coordinated modes of metal centers with halogen, which accordingly led to the change of the C-H...Cl(Br) interactions in the complexes.
