Temperature and solvent controlled syntheses of six hydrous 5-(3-pyridylmethoxy)isophthalate Cd(II) coordination polymers

Six Cd(II) coordination polymers based on 5-(3-pyridylmethoxy)isophthalic acid were synthesized. These Cd(II) complexes possess different coordinated and/or lattice water molecules, and exhibit various structural features and topology nets. Temperature and solvent play crucial roles in the preparation reactions. A little change of temperature or solvent can greatly affect their hydration and structures. The coordination polymers exhibit high thermal stability and emit green luminescence.
