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, N2H5+.C4H5O4–, 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 N2H5+ ions, thus forming a three-dimensional network. The salt undergoes melting followed by decomposition to give gaseous products.
