(Int Union Crystallography, 2020)
The asymmetric unit of the title compound, C5H7N2O+center dot C4H4NO4S-, contains one cation and one anion. The 6-methyl-2,2,4-trioxo-2H,4H-1,2,3-oxathiazin-3-ide anion adopts an envelope conformation with the S atom as ...
Crystal structure of (E)-2,6-dimethoxy-4-{[(4-methoxyphenyl)imino]methyl}phenol
(Int Union Crystallography, 2018)
In the title compound, C16H17NO4, the dihedral angle between benzene rings is 72.7 (2)degrees. The methoxy groups are rotated by 2.4 (2) and -4.9 (2) (benzilidene moiety) and by 5.6 (3)degrees (aniline moiety) relative to ...
Crystal structure and DFT study of 8-hydroxy-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinoline-9-carbaldehyde
(Int Union Crystallography, 2017)
In the title compound, C13H15NO2, the fused non-aromatic rings of the julolidine moiety adopt envelope conformations. The hydroxy group forms an intramolecular hydrogen bond to the aldehyde O atom, generating an S(6) ring ...
Redetermination of the crystal structure of bis(tri-2-pyridylamine)iron(II) bis(perchlorate), and a new refinement of the isotypic nickel(II) analogue: treatment of the perchlorate anion disorder
(Int Union Crystallography, 2018)
The redetermination of the structure of the title compound, [Fe(C15H12N4)(2)](ClO4)(2), (I), confirms the structure previously reported [Kucharski et al. (1978a). Aust. J. Chem. 31, 53-56], but models the perchlorate over ...
Crystal structure and Hirshfeld surface analysis of tetraaquabis(isonicotinamide-kappa N-1) nickel(II) fumarate
(Int Union Crystallography, 2018)
The reaction of NiCl2 with fumaric acid and isonicotinamide in a basic solution produces the title complex, [Ni(C6H6N2O)(2)(H2O)(4)](C4H2O4). The nickel(II) ion of the complex cation and the fumarate anion are each located ...
