(E)-4-[4-(Diethyl-amino)-benzyl-idene-ammonio]-benzene-sulfonate.

Project description:The title compound, C(17)H(20)N(2)O(3)S, synthesised from sulfanilic acid and 4-diethyl-amino-benzaldehyde, crystallized out as a zwitterion with the central N atom protonated. The zwitterion exists in an E conformation with respect to the C=N double bond. The dihedral angle between the benzene rings is 37.57 (5)°. In the crystal, the zwitterions are linked into a tape along the a axis by N-H⋯O hydrogen bonds. The crystal structure is further stabilized by weak C-H⋯O inter-actions and π-π inter-actions with a centroid-centroid distance of 3.8541 (6) Å. An O⋯O [2.8498 (11) Å] short contact is present.

4-[(2,4-Dihydroxy-benzyl-idene)ammonio]benzene-sulfonate trihydrate.

Project description:The title Schiff base compound, C(13)H(11)NO(5)S·3H(2)O, formed from sulfanilic acid and 2,4-dihydroxy-benzaldehyde, crystallized out as a zwitterion with the N atom protonated. The asymmetric unit consists of one 4-[(2,4-dihydroxy-benzyl-idene)ammonio]benzene-sulfonate and three water mol-ecules. The zwitterion exists in an E configuration with respect to the central C=N double bond. The two benzene rings of the mol-ecule are oriented at a dihedral angle of 27.33?(8)°. An intra-molecular N-H?O hydrogen bond stabilizes the mol-ecular structure. In the crystal, the zwitterions are linked into chains along [101] by inter-molecular O-H?O and N-H?O hydrogen bonds. The three water mol-ecules link these chains into a three-dimensional framework by additional inter-molecular O-H?O hydrogen bonds. A ??? inter-action [3.5485?(9)?Å] further stabilizes the crystal structure.

4-{[4-(Di-methyl-amino)-benzyl-idene]amino}-benzene-sulfonamide.

Project description:The title Schiff base compound, C15H17N3O2S, is non-planar with a dihedral angle of 69.88?(4)° between the planes of the benzene rings. In the crystal, pairs of N-H?N hydrogen bonds, between the sulfonamide nitro-gen-H atom and the azomethine N atom, link the mol-ecules into inversion dimers, forming R 2 (2)(16) ring motifs. These dimers are linked by N-H?O hydrogen bonds, between the sulfonamide nitro-gen-H atom and one sulfonamide O atom, forming sheets lying parallel to (100). Within the sheets there are weak parallel slipped ?-? inter-actions involving inversion-related benzene-sulfonamide rings [centroid-centroid distance = 3.8800?(9)?Å; normal distance = 3.4796?(6)?Å; slippage = 1.717?Å].
