Hydrothermal synthesis, crystal structure and properties of a 1D metal-organic coordination polymer {[Zn_2(2,2′,3,3′-odpa) (py)_3(H_2O)]·H_2O}_n

摘要

Hydrothermal reaction of Zn(NO_3)_2·6H _2O with 2,2′,3,3′-oxydiphthalic acid (H_4odpa) and pyridine (py) at 120 °C yielded a one-dimensional metal-organic coordination polymer {[Zn2(2,2′,3,3′-odpa)(py)_3(H _2O)]·H_2O}_n (1), which is further connected together through hydrogen bonds, π?π and C-H?π interactions to give a three-dimensional supramolecular network. The thermal stability of complex 1 was studied by thermal gravimetric (TG) and differential thermal analyses (DTA). Compound 1 exhibits photoluminescence with an emission maximum at ca. 430 nm upon excitation at 350 nm.
