abstract = {Two new coordination polymers (CPs) based on Zn(II) and Cd(II) and 1H-indazole-6-
carboxylic acid (H2L) of general formulae [Zn(L)(H2O)]n (1) and [Cd2
(HL)4
]n (2) have been synthesized and fully characterized by elemental analyses, Fourier transformed infrared spectroscopy and
single crystal X-ray diffraction. The results indicate that compound 1 possesses double chains in
its structure whereas 2 exhibits a 3D network. The intermolecular interactions, including hydrogen
bonds, C–H···π and π···π stacking interactions, stabilize both crystal structures. Photoluminescence
(PL) properties have shown that compounds 1 and 2 present similar emission spectra compared to
the free-ligand. The emission spectra are also studied from the theoretical point of view by means
of time-dependent density-functional theory (TD-DFT) calculations to confirm that ligand-centred
π-π* electronic transitions govern emission of compound 1 and 2. Finally, the PL properties are also
studied in aqueous solution to explore the stability and emission capacity of the compounds.},
