Quinolinium 8-hydroxy-7-iodoquinoline-5-sulfonate 0.8-hydrate
In the crystal structure of the title hydrated quinolinium salt of ferron (8-hy-droxy-7-iodo-quinoline-5-sulfonic acid), C9H7N(+)·C9H5INO4S(-)·0.8H2O, the quinolinium cation is fully disordered over two sites (occupancy factors fixed at 0.63 and 0.37) lying essentially within a common plane and with the ferron anions forming π-π-associated stacks down the b axis [minimum ring centroid separatio...
متن کاملBis(guanidinium) 4,5-dichlorophthalate monohydrate
In the structure of the title hydrated salt, 2CH(6)N(3) (+)·C(8)H(2)Cl(2)O(4) (2-)·H(2)O, the planes of the carboxyl-ate groups of the dianion are rotated out of the plane of the benzene ring [dihedral angles = 48.42 (10) and 55.64 (9)°]. A duplex-sheet structure is formed through guanidinium-carboxyl-ate N-H⋯O, guanidinium-water N-H⋯O and water-carboxyl-ate O-H⋯O hydrogen-bonding associations.
متن کامل8-Quinolyl 5-(dimethylamino)naphthalene-1-sulfonate
In the title compound, C(21)H(18)N(2)O(3)S, the dihedral angle between the naphthalene and quinoline ring systems is 55.53 (2)°, and the torsion angle involving the connecting C-S-O-C atoms is 87.60 (3)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds connect mol-ecules into chains along [100] and there are π-π stacking inter-actions between pairs of chains with a centroid-...
متن کامل4-Aminopyridinium-3-sulfonate monohydrate
The reaction of 4-amino-pyridine and oleum yielded the title hydrated zwitterion, C(5)H(6)N(2)O(3)S·H(2)O. There are two formula units in the asymmetric unit. The H and non-H atoms of both zwitterions lie on a mirror plane except for one sulfonate O atom. The water mol-ecules are also situated on a mirror plane. In the crystal, the zwitterions and water mol-ecules are linked by O-H⋯O and N-H⋯O ...
متن کاملGuanidinium 3-carboxy-2,3-dihydroxypropanoate monohydrate
In the title hydrated salt, CH(6)N(3) (+)·C(4)H(5)O(6) (-)·H(2)O, the deprotonated carboxyl group is disordered over two positions with a site-occupancy ratio of 0.945 (3):0.055 (3). The bond lengths in the guanidinium cation are inter-mediate between normal C-N and C=N bond lengths, indicating significant delocalization in this species. In the crystal structure, anions and water mol-ecules are...
