Abstract:Two novel cyclohexane-like metallamacrocycles ZnCH3COO(L)]6·solvent (1) and Zn(HNO3)(L)]6·solvent (2) (HL = 4′-(4-carboxyphenyl)-2,2′:6′,2″-terpyridine) have been synthesized under hydrothermal conditions and characterized by IR spectra, single crystal X-ray diffraction, PXRD analysis, thermogravimetric analysis. The X-ray single crystal diffraction indicates that the self-assembly of the metallamacrocycle generates a fused-ring network that is further assembled into a 3D structure with 1D suprachannels. In particular, a designed self-assembly strategy has been applied to achieving six-membered Zn–organic metallamacrocycles unprecedentedly.
