In situ facile nitration in hydrothermal reaction generating novel metal-organic coordination polymer

摘要

The first in situ nitration substitution was hydrothermally achieved only by lead(II) nitrate rather than HNO_3/H_2SO_4. The new organic ligand, 4,6-dinitro-5-oxido-1,3-benzenedicarboxylate (dnob~(3-)) in situ synthesized from 5-hydroxyl-1,3-benzenedicarboxylic acid, exhibits interesting steric and electronic effects on the assembly of lead(II) coordination polymer, [Pb_3(dnob)_2(phen)3(H_2O)]_n where phen is 1,10-phenanthroline.
