Abstract

The reaction of cadmium nitrate, terephthalic acid (Bdc), and 1,4-diazabicyclo[2.2.2]octane (Dabco) in N,N-dimethylformamide affords the new coordination polymer [Cd2(Bdc)2Dabco] (I), whose structure is determined by X-ray diffraction (CIF file CCDC no. 2441975). This coordination polymer (or metal-organic framework) demonstrates high thermal stability: the fast mass loss starts at temperatures above 420°C. Compound I exhibits photoluminescence at 430 nm (λex = 380 nm) with lifetimes of 5 and 12 ns and a quantum yield of 6%.
