Title: | 2-Amino-5-nitro-pyridinium tetraoxido-rhenate(VII) monohydrate | Authors: | Rodrigues, V. H. Costa, M. M. R. R. Dekola, T. Gomes, E. de Matos |
Keywords: | single-crystal X-ray study; T = 295 K; mean (C–C) = 0.004 A°; R factor = 0.015; wR factor = 0.033; data-to-parameter ratio = 15.0 | Issue Date: | 29-Jul-2009 | Publisher: | International Union of Crystallography | Project: | FCT | Serial title, monograph or event: | Acta Crystallographica Section E: Structure Reports Online | Volume: | 65 | Issue: | Pt 8 | Abstract: | All the residues of the title compound, (C(5)H(6)N(3)O(2))[ReO(4)]·H(2)O, are located on general crystallographic positions. The 2-amino-5-nitro-pyridinium cation has a typical planar conformation with one of the nitro O atoms -0.058 (5) Å out of plane; the amine H atoms are also a little out of the main ring plane towards the opposite side of the aforementioned O atom [by 0.02 (4) and 0.04 (4) Å]. The perrhenate anion is nearly ideally tetra-hedral. Three distinct N-H⋯O hydrogen bonds give rise to C(8) zigzag chains running along [100]. R(4) (4)(12) rings involving the two hydrogen bonds in which the water mol-ecules inter-act with the perrhenate anions are also present. | URI: | https://hdl.handle.net/10316/110231 | ISSN: | 1600-5368 | DOI: | 10.1107/S1600536809029365 | Rights: | openAccess |
