Crystal structure of 2-amino-5-nitropyridinium sulfamate

Abstract

The title mol­ecular salt, obtained by the reaction of sulfamic acid with 2-amino-5-nitro­pyridine, is the result of a proton transfer from sulfamic acid to the N atom of the pyridine ring. In the crystal, the cations and anions are linked by a number of N—H⋯O and N—H⋯N hydrogen bonds, forming sheets lying parallel to (100).

“…Hydrazone derivatives containing an azomethine (-CONHN CH-) group act as cytotoxic agents with the capability to prevent cell series in cancerous cells through different mechanisms (Patil et al, 2011). Pyridine heterocycles and their derivatives are present in many large molecules having photo-chemical, electrochemical and catalytic applications (Thirunavukkarsu et al, 2017;Venda et al, 2017;Jauhar et al, 2016;Babu et al, 2014aBabu et al, ,b, 2015Rajkumar et al, 2014Rajkumar et al, , 2015Huq et al, 2010). As a part of our research study, we report herein the synthesis and the crystal structures of the title compounds, (I) and (II), which contain several donor functions of a different nature: hydrazide and pyridine.…”

“…Pyridine heterocycles and their derivatives have large applications in the field of photo-chemical, electrochemical and catalytic process. Some pyridine derivatives possess non-linear optical (NLO) properties (Rajkumar et al, 2015). The crystal structure of 2-aminopyridinium isonicotinate 2-aminopyridine has already been reported (Xie, 2007).…”

Growth and characterization studies of an efficient semiorganic NLO single crystal: 2-Amino 5-nitropyridinium sulfamate (2A5NPS) by assembled temperature reduction (ATR) method

“…The efficient semi organic crystal of 2-amino 5-nitropyridinium dihydrogen phosphate (2A5NPDP) was grown by using sankaranarayanan-ramasamy (S-R) method and optical, electrical, mechanical and NLO properties were reported [29,30]. The grown crystal of 2-amino 5-nitropyridinium sulfamate (2A5NPS) structure was solved and reported [31]. In this article, we report the synthesis and growth of 2-amino 5-nitropyridinium sulfamate (2A5NPS) by slow cooling method.…”
