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

The first in situ nitration substitution was hydrothermally achieved only by lead(II) nitrate rather than HNO3/H2SO4. The new organic ligand, 4,6-dinitro-5-oxido-1,3-benzenedicarboxylate (dnob3−) in situ synthesized from 5-hydroxyl-1,3-benzenedicarboxylic acid, exhibits interesting steric and electronic effects on the assembly of lead(II) coordination polymer, [Pb3(dnob)2(phen)3(H2O)]n where phen is 1,10-phenanthroline.
