Positional isomeric effect on the structural variation of Cd(<scp>ii</scp>) coordination polymers based on flexible linear/V-shaped bipyridyl benzene ligands

Abstract

Solvothermal reactions of Cd(OAc)₂·2H₂O with 2,2′-azodibenzoic acid and five positional isomeric N-donor bipyridyl benzene ligands in MeOH/H₂O at 170 °C gave rise to five coordination polymers. Complexes <bold>1–5</bold> were characterized by elemental analysis, IR spectroscopy, powder X-ray diffraction, and single-crystal X-ray diffraction.
