(E)-2-[4-(Diethyl-amino)-styr-yl]-1-methyl-pyridinium 4-meth-oxy-benzene-sulfonate monohydrate.

ABSTRACT: In the cation of the title compound, C(18)H(23)N(2) (+)·C(7)H(7)O(4)S(-)·H(2)O, one ethyl group of the diethyl-amino unit is disordered over two sets of sites in a 0.665?(6):0.335?(6) ratio. The styrylpyridinium unit is nearly planar, with a dihedral angle between the pyridinium and benzene rings of 4.27?(8)°. In the crystal, the anion ring is almost perpendicular to the aromatic rings of the cation; the sulfonate-substituted benzene ring forms dihedral angles of 89.60?(8) and 89.37?(8)°, respectively, with the pyridinium and benzene rings of the cation. In the crystal, the three components are linked into a three-dimensional network by O-H?O and C-H?O hydrogen bonds. ?-? inter-actions with centroid-centroid distances of 3.6999?(9) and 3.7106?(9)?Å are also present.

2-Amino-4-methyl-pyridinium 3-carb-oxy-4-hy-droxy-benzene-sulfonate monohydrate.

Project description:In the crystal structure of the title salt, C(6)H(9)N(2) (+)·C(7)H(5)O(6)S(-)·H(2)O, the water mol-ecule acts as an acceptor of bifurcated N-H?O hydrogen bonds from the pyridinium H atom and one H atom of the 2-amino group, forming an R(2) (1)(6) ring. The 3-carb-oxy-4-hy-droxy-benzene-sulfonate anions self-assemble via O-H?O hydrogen bonds, leading to supra-molecular chains along the a axis. These chains and R(2) (1)(6) motifs are linked via O-H?O, N-H?O and C-H?O hydrogen bonds, forming a layer parallel to the ac plane. There is also an intra-molecular O-H?O hydrogen bond in the 3-carb-oxy-4-hy-droxy-benzene-sulfonate anion, generating an S(6) ring motif.
