Two pH-dependent heteronuclear coordination polymers using 1,3,5-benzenetricarboxyl acid ligand have been synthesized.
5">The ligand in compound 2 is oxidized into 2-hydroxytrimesic acid and shows totally different 3D structure compared with 1.
The structures of the compounds are determined by X-ray study.
5">The coordination polymers are characterized by IR, luminescence and TGA techniques.
