Synthesis and spectroscopic, thermal and crystal structure studies of hydrazinium hydrogensuccinate

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, N⁺.C^-, 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 throughO- H···N and bifurcatedN-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 N⁺ ions, thus forming a three-dimensional network. The salt undergoes melting followed by decomposition to give gaseous products.
