Two novel coordination polymers obtained by hydrothermal reaction of Ag(I) nitrate and Cd(II) acetate salts with 3,5-dichloroisonicotinic acid and 1,3-bis(4-pyridyl)propane flexible ligand have been synthesized and characterized by single crystal X-ray diffraction (CIF files nos. 2082469 (I) and 2082471 (II)), elemental analyses, thermogravimetric analyses, powder X-ray diffractions and fluorescent spectra, formulated as {[Ag(Bpp)](Dcia)}n (I) and [Cd(Dcia)2(Bpp)2]n (II) (HDcia = 3,5-dichloroisonicotinic acid, Bpp = 1,3-bis(4-pyridyl)propane). The single-crystal X-ray diffractions reveal that two complexes show different 2D {63} hcb topological nets and (4,4) grid layers displaying remarked structural sensitivity to metal cation. Among them, complex I displays 2D unusual cationic layer developed by T-shaped Bpp-bridging Ag–Ag building units. Complex II exhibits 2D grid layer jointed by Dcia ligand with dangling Bpp ligand, which further interlinked into 3D supramolecular architecture by π–π interactions. In addition, luminescent properties of both complexes are also systematically investigated. [ABSTRACT FROM AUTHOR] |
