2-[(E)-2-(4-Chloro­phen­yl)ethen­yl]-1-methyl­pyridinium 4-chloro­benzene­sulfonate

In the title salt, C(14)H(13)ClN(+)·C(6)H(4)ClO(3)S(-), the cation exists in an E configuration with respect to the ethynyl bond and is approximately planar, with a dihedral angle of 3.4 (2)° between the pyridinium and benzene rings. The anion is approximately perpendicular to the cation plane, the benzene ring of the anion making dihedral angles of 89.4 (2) and 89.9 (2)°, respectively, with th...

2-[(E)-2-(4-Chloro­phen­yl)ethen­yl]-1-methyl­pyridinium 4-methoxy­benzene­sulfonate

In the asymmetric unit of the title salt, C(14)H(13)ClN(+)·C(7)H(7)O(4)S(-), there are two crystallographically independent mol-ecules for each component. Each cation adopts an E configuration with respect to the C=C bond and is slightly twisted; the dihedral angle between the pyridinium and benzene rings is 6.53 (7)° for one mol-ecule and 5.30 (7)° for the other. The meth-oxy groups in the ani...

In the title compound, C(14)H(13)ClN(+)·C(6)H(4)BrO(3)S(-), the cation exists in an E configuration with respect to the ethenyl bond and is almost planar, the dihedral angle between the pyridinium and the benzene rings being 2.80 (7)°. The dihedral angles between the benzene ring of the anion and the pyridinium and benzene rings of the cation are 80.88 (7) and 79.05 (7)°, respectively. In the c...

In the structure of the title salt, C20H20NO(+)·C6H4FO3S(-), the 4-(eth-oxy-phen-yl)ethenyl unit is disordered over two positions with a refined site-occupancy ratio of 0.610 (6):0.390 (6). The cation is nearly planar, the dihedral angle between the quinolinium and benzene rings being 6.7 (4) and 1.7 (7)° for the major and minor components, respectively. The eth-oxy group is essentially coplana...

(E)-1-(4-Nitro­phen­yl)-2-(4-{[(E)-2-(4-nitro­phen­yl)hydrazinyl­idene]meth­yl}benzyl­idene)hydrazine dihydrate

The 30 non-H atoms in title dihydrazine compound, C(20)H(16)N(6)O(4)·2H(2)O, are close to coplanar, the r.m.s. deviation for these atoms being 0.096 Å. The conformation about each of the C=N bonds is E, and the mol-ecule has non-crystallographic 2/m symmetry. The presence of O-H⋯O and N-H⋯O hydrogen bonding leads to a three-dimensional network in the crystal structure. A highly disordered solve...
