PREMKUMAR, Thathan; SELVAKUMAR, Rajendran; RATH, Nigam P  and  GOVINDARAJAN, Subbiah. Synthesis and Spectroscopic, Thermal and Crystal Structure Studies of Hydrazinium Hydrogensuccinate. S.Afr.j.chem. (Online) [online]. 2014, vol.67. ISSN 1996-840X.

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

Keywords : Hydrazine; succinic acid; hydrazinium hydrogensuccinate; crystal structure; thermal studies.
