Sodium and lithium one-dimensional coordination polymers with 1H-indazole-3-carboxylic acid: Crystal structures, vibrational spectra and DFT calculations

Coordination sphere hydrogen bonding as a structural element in metal–organic Frameworks

“…The group of Morzyk-Ociepa and co-workers reported the crystal structures of polymeric alkali metal complexes of HL11. 73 In those structures, a uniform chelating μ 2 -κN,O:κO′ coordination mode was displayed by the ligand which coordinates in a monoanionic coordination mode, leaving the indazole N-H group free to participate in intramolecular hydrogen bonding to support the rod-shaped building units. Meanwhile, Garcıá-Valdivia et al have recently explored H 2 L10 and H 2 L13 as linkers.…”
