摘要:
A one-dimensional (1-D) coordination polymer, {[Cd2L (pp)2 (H2O)](H2O)2.5}n (L = tetrahydrofuran-2,3,4,5-tetracarboxylate and pp = 3-(2-pyridyl)pyrazole) was synthesized and structurally characterized by single crystal X-ray diffraction analysis. This complex belongs to monoclinic system with space group P2(1)/n. Adjacent dinuclear nodes are alternately bridged by L ligands to form a 1-D ribbon-shaped structure. In addition, such 1-D chains above are further linked by interchain OHO and CHO hydrogen-bonding interactions along the different crystallographic directions, generating an overall three-dimensional (3D) supramolecular framework. Studies on photoluminescent properties of this complex show the solid-state blue emission originating from an intraligand * transition of chelating pp co-ligand.
