【 摘 要 】

Two new coordination polymers of Zn(II) and Cd(II) have been synthesized using 2,4,6-tri(4-pyridyl)-1,3,5-triazine (tpt), where it acts as a bi-bridging ligand. The compounds are characterized by IR spectroscopy, elemental analysis and single crystal X-ray diffraction studies. Compound [Zn(tpt)(NO3)2(H2O)2]𝑛 (1) and [Cd(tpt)(NO3)2(H2O)2]𝑛 (2) are isomorphous and show 1D coordination structure with almost octahedral metal center, which is extended to supramolecular 3D structure by cooperative weak interactions, like H-bonding, 𝜋-𝜋 and C-H…O interactions. Both the compounds reveal interplay of covalent and non-covalent interactions for fabricating supramolecular solid-state architecture.
