摘要
Two new metal-organic entangled frameworks, namely [Cd(FA)(0.5)(bix)(1.5)(H2O)] (n) center dot nNO(3) (1) and [Cd(FA)(bib)(H2O)(2)] (n) (2) (FA = fumaric acid, bix = 4,4'-bis(imidazol-1-ylmethyl)benzene, bib = 1,4-bis(imidazolyl)butane), have been successfully hydrothermally synthesized through mixed ligands strategy. Single crystal X-ray diffraction analysis reveal that 1 is a 2D -> 3D polycatenated framework, while 2 is a triply interpenetrated 4-connected dia topological net. Moreover, both compounds exhibit intense luminescence emission at room temperature.
