Adeninium perchlorate

Abstract

In the title salt (systematic name: 6-amino-9H-purin-1-ium perchlorate), C5H6N5 +·ClO4 −, the adeninium cation is essentially planar, with a maximum deviation of 0.038 (1) Å. The whole of the perchlorate anion is disordered over two sets of sites with an occupancy ratio of 0.589 (13):0.411 (13). In the crystal, the adeninium cations are linked by pairs of N—H⋯N hydrogen bond into inversion dimers. The dimers and the anions are further inter­connected into a three-dimensional supra­molecular structure via inter­molecular N—H⋯O, C—H⋯O and C—H⋯N hydrogen bonds.

“…4). This homosynthon (10) motif that mimics the Hoogsteen pattern has been observed in similar adenine-based hybrid compounds formed with different oxoanions, namely; bis adeninium dinitrate monohydrate [36], adeninium perchlorate adenine dihydrate [50] and adeninium perchlorate [51]. Despite the fact that the adeninium-anion supramolecular heterosynthon motifs are one of the classic motifs frequently observed in similar structures [52], we however note their total absence in the title compounds.…”

“…In 1984 Kaim has reported the carbonyl substitution reactions of M(CO) 6 (M = Cr, Mo, W) with the radical anions of ligands 1 , 2 , and 3 , which result in the replacement of CO and the formation of mononuclear paramagnetic complexes at first and then get converted to binuclear paramagnetic complexes . Subsequently, the mononuclear Ni, Co, Cu, Zn, Hg, Ru, , Os, and Ir complexes based on the ligands 2 and 3 were reported. The first report bearing Se···N SBIs for the construction of periodic supramolecular architectures reported was by Tong and co-workers .…”

“…Recently, similar structures containing adeninium cations have been reported. Among examples, can be named the following ones: Adeninium diperchlorate monohydrate (Bendjeddou et al, 2003), and Adeninium perchlorate (Fun et al, 2011). In the structure of (I), the ions are held together with intermolecular N-H…”
