2-pyridiniohydrazinium dichloride

Abstract

The crystal structure of the title compound, C5H9N32+center dot 2Cl(-), is stabilized by N-H center dot center dot center dot Cl hydrogen bonds, forming a three-dimensional network. Each chloride anion forms three hydrogen bonds with N atoms, and the hydrazine unit forms R-2(1)(5) motifs with one of the Cl- anions. The aromatic ring is almost coplanar with both the N atoms of the hydrazine substituent and with one of the Cl- anions.
