Abstract: A new organophosphonate ligand containing sulfide group, 4-pyridylthioethylphosphonic acid hydrobromide (H2pytep·HBr), is synthesized through a facile route. Two zinc complexes of Zn2(pytepH2)2Br4 (1) and [Zn(pytep)]·H2O (2) are obtained by reacting H2pytep·HBr with zinc nitrate in solution and under hydrothermal condition, respectively. X-ray crystallographic studies reveal that 1 has a dinuclear structure in which the equivalent Zn atoms are doubly bridged by phosphonate groups. Compound 2 has a layer structure where ladder-like chains made up of corner-sharing {ZnNO3} and {CPO3} tetrahedra are linked by the organic groups of pytep. Photoluminescent properties are investigated. Different from complex 1 which shows no photoluminescence, complex 2 exhibits photoluminescence at 468nm (λ ex =353nm) in the solid state at room temperature. [Copyright &y& Elsevier] |
