Abstract
- Six hydrous Cd(II) coordination polymers based on a scorpion-like 5-(3-pyridylmethoxy)isophthalic acid (H 2 L), namely {[CdL(H 2 O)]·2H 2 O} n ( 1 ), [Cd 4 L 4 (H 2 O) 4 ] n ( 2 ), [CdL(H 2 O)] n ( 3 ), [CdL(H 2 O) 2 ] n ( 4 ), {[CdL(H 2 O)]·H 2 O} n ( 5 ) and [CdL] n ( 6 ), were hydrothermally synthesized and characterized by EA, IR, PXRD, TG-DSC and X-ray structural analysis. Temperature and solvent play crucial roles in the preparation of the coordination polymers. Complexes 1 – 3 were prepared in a H 2 O-DMF (6:2) solvent system at slightly different temperature (85, 100 and 120 °C). Complexes 4 – 6 were prepared in different H 2 O-DMF solvents (6:3 and 8:2) and H 2 O-MeCN (3:6) solvent. These complexes possess different coordinated and/or lattice water molecules, and exhibit structural diversity and various topology nets. Complex 1 is a 2D double-layered coordination polymer. Complex 2 features a 3D porous framework with irl topology. Complex 3 displays a 2D double-layered network. Complex 4 is a 3D coordination polymer with sra topology. Complex 5 exhibits a 3D wave-like framework with sra topology. Complex 6 is a 3D coordination polymer with self-catenated hxg-d topology. 5-(3-Pyridylmethoxy)isophthalate adopts three types of coordination modes. These complexes exhibit higher thermal stability and emit strong luminescence. [ABSTRACT FROM AUTHOR]
