Structural study of pyridine-2,6-dicarbohydrazide nitrate salt

摘要

Reaction between dimethyl-2,6-pyridinedicarboxylate and anhydrous hydrazine by microwave synthesis under solvent free conditions gave pyridine-2,6-dicarbohydrazide (pdch). This compound was recrystallized in methanol at low pH condition andgavethe nitrate salt of pdch. In the crystal structure of this compound, protonated pdch cations and nitrate anions are linkedvia N−H···Nnitrateand N−H···Onitratehydrogen bonds into a three-dimensional network. The structure features extensive hydrogen bonding, with 13 distinct interactions. There are also weak intermolecular interactions includingO···π, O···O and N−H···π.
