The mono-hydrazinium salt of succinic acid (hydrazinium hydrogensuccinate salt) was prepared by reacting hydrazine hydrate and succinic acid. Its spectral, thermal and structural properties have been determined. The salt, NH+.CHO-, is a molecular salt containing discrete hydrazinium cations and hydrogen succinate anions. The crystal packing consists of infinite chains of anions and cations that are alternatively linked through O-H∙∙∙N and bifurcated N-H∙∙∙O bonds and this chain is connected to adjacent antiparallel chains by N-H∙∙∙O hydrogen bonding. The adjacent chains are cross linked by N-H∙∙∙O bonds from the donor NH+ ions, thus forming a three-dimensional network. The salt undergoes melting followed by decomposition to give gaseous products.
