In the title compound, C(14)H(11)BrN(2)O(4), the amide segment makes dihedral angles of 23.4 (2) and 20.5 (2)° with the benzene rings, while the dihedral angle between the bezene rings is 2.90 (8)°. The nitro and meth-oxy groups are almost coplanar with their bound benzene ring, with the r.m.s. deviation for the 11 non-H atoms being 0.0265 (1) Å. An(More)
Mol-ecules of the title compound, C16H16N4O7, are not planar with a dihedral angle of 5.50 (11)° between the substituted benzene rings. The two meta-meth-oxy groups of the 3,4,5-tri-meth-oxy-benzene moiety lie in the plane of the attached ring [Cmeth-yl-O-C-C torsion angles -0.1 (4)° and -3.7 (3)°] while the para-meth-oxy substituent lies out of the plane(More)
In the asymmetric unit of the title chalcone derivative, C(18)H(19)NO(4), there are three crystallographically independent mol-ecules (mol-ecules A, B and C). In mol-ecule A, the dihedral angle between two benzene rings is 12.22 (10)° and the plane of the central prop-2-en-1-one unit makes dihedral angles of 11.02 (13) and 2.64 (12)° with the two adjacent(More)
Mol-ecules of the title amino-chalcone, C(18)H(19)NO(4), are twisted, with a dihedral angle of 11.26 (6)° between the 4-amino-phenyl and 2,4,5-trimeth-oxy-phenyl rings. The conformations of the three meth-oxy groups with respect to the benzene ring are slightly different. Two meth-oxy groups are almost coplanar with the attached benzene ring [C-O-C-C(More)
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(More)
The mol-ecule of the title heteroaryl chalcone derivative, C13H11NOS, exists in a trans-configuaration and is almost planar with a dihedral angle of 3.73 (8)° between the phenyl and thio-phene rings. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, two adjacent mol-ecules are linked into a dimer in an anti-parallel(More)
The mol-ecule of the title benzamide derivative, C(13)H(10)BrNO, is twisted with the dihedral angle between the phenyl and 4-bromo-phenyl rings being 58.63 (9)°. The central N-C=O plane makes dihedral angles of 30.2 (2) and 29.2 (2)° with the phenyl and 4-bromo-phenyl rings, respectively. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into(More)
In the title 3-cyano-pyridine derivative, C21H19N3O4, the 3-cyano-substituted pyridine ring forms dihedral angles of 2.35 (5) and 41.60 (5)° with the unsubstituted pyridine and 2,4,5-trimeth-oxy-substituted benzene rings, respectively. The dihedral angle between the unsubstituted pyridine and benzene rings is 39.84 (5)°. The meth-oxy groups form(More)
The asymmetric unit of the title compound, C(17)H(20)NO(3) (+)·C(6)H(5)O(3)S(-)·H(2)O, comprises two 1-methyl-2-[(E)-2,4,5-trimeth-oxy-styr-yl]pyridinium cations, two benzene-sulfonate anions and two water mol-ecules. The cations exist in the E conformation with respect to the C=C bond; one cation is essentially planar while the other is slightly twisted,(More)
In the title compound, (C(19)H(18)NO(2))(2)[ZnI(4)]·CH(3)OH, each cation is nearly planar and exists in an E configuration, the dihedral angles between the quinolinium systems and the benzene rings being 1.78 (10) and 5.44 (10)° for the two cations. The [ZnI(4)](2-) anion displays a very slightly distorted tetra-hedral geometry. There are intra-molecular(More)
