Syntheses, Structures, and Luminescence Property of Two New Supramolecular Complexes Containing a Flexible Carboxylate

Abstract

Two new complexes, namely [Cd(L) 2 (2,2 0 -bipy)] (1) and [(HL)(4,4 0 -bipy) 0.5 ((H 2 O)] (2) (HL D 3-(2-hydroxyphenyl)propanoic acid, 2,2 0 -bipy D 2,2 0 -bipyridine and 4,4 0 -bipy D 4,4 0 -bipyridine), have been synthesized and structurally characterized by single-crystal diffraction analysis. The structure of complex 1 is molecular dimer, which is connected by stronger hydrogen bond interactions to result in a 2D network. While complex 2 is composed of two organic ligands molecular dimer and one water molecule, which also could be linked into a 2D supramolecular architecture via hydrogen bond interactions. Luminescence and its lifetime for compound 1 have also been explored.

Influence of a series of pyridine ligands on the structure and photophysical properties of Cd(ii) complexes

“…The bond lengths and angles are in the range of 2.3162( 16)-2.4423( 14) Å and 54.58(4)-142.45( 5)°(ESI: † Table S3), which are similar to that of other reported hepta-coordinated Cd(II) compounds containing carboxylate ligands and 2,2′-bipy. [46][47][48] Additionally, its crystal structure presents two occluded MeOH molecules.…”
