The title compound, C(16)H(19)N(3)O(4)S, is almost planar, with a dihedral angle of 2.88 (9)° between the mean planes of the benzene and thia-zole rings. The mol-ecule adopts an E conformation about the two C=N bonds, with a C-N-N-C torsion angle of -177.01 (11)°. An intra-molecular C-H⋯O hydrogen bond exists between a thia-zole methyl group and the formic(More)
The asymmetric unit of the title compound, C(16)H(13)N(2)O(+)·NCS(-)·C(16)H(12)N(2)O, contains two N-(pyridin-4-yl)naphthalene-2-carboxamide mol-ecules, both are partially protonated in the pyridine moiety, i.e. the H atom attached to the pyridine N atom is partially occupied with an occupancy factor of 0.61 (3) and 0.39 (3), respectively. In the crystal,(More)
In the title mol-ecule, C24H28N2O3, the cyclo-hexene ring is in a sofa conformation and the 1,4-dihydro-pyridine ring is in a slight boat conformation. In the indole ring system, the pyrrole and benzene rings form a dihedral angle of 2.63 (7)°. In the crystal, N-H⋯O hydrogen bonds connect the mol-ecules into C(6) chains parallel to the b axis and pairs of(More)
In the title compound, C(19)H(25)N(3)O(5), the benzene ring is not coplanar with the amide group [dihedral angle = 61.90 (5)°]. The cyclo-hexyl rings are in chair conformations. There is a strong inter-molecular inter-action between the C=O group of the amide group and the nitro group of an adjoining mol-ecule, with a short O⋯N distance of 2.7862 (17) Å. In(More)
The title compound, C(19)H(26)N(2)O(3), crystallizes with two independent mol-ecules in the asymmetric unit which differ in the twist of the phenyl rings with respect to the plane of the amide group [the C-C-C-O torsion angles are 121.5 (3) and -119.6 (3)° in the two mol-ecules. Both cyclo-hexane rings adopt chair conformations. In the crystal, weak C-H⋯O(More)
In the title compound, C21H19BrN2O2·C2H6OS, the indole ring system is essentially planar, with a maximum deviation of 0.050 (3) Å for the non-bridgehead C atom adjacent to the N atom. The two cyclo-hex-2-enone rings adopt half-chair conformations. An intra-molecular C-H⋯O hydrogen bond occurs. The solvent mol-ecule exhibits minor disorder of the S atom(More)
In the title compound, [Pb(C14H14O2PS2)2] n , the metal atom is surrounded by two O,O'-bis-(2-methyl-phen-yl) dithio-phosphate ligands bonding through the S-donor atoms. Three of the Pb-S bond lengths are are close to each other at 2.7710 (18), 2.8104 (16) and 2.8205 (16) Å, while the fourth Pb-S bond is elongated at 3.0910 (18) Å and reflects the fact that(More)
The title compound, C23H25BrN2O3, crystallizes with two independent mol-ecules in the asymmetric unit (Z' = 2) which differ in the twist of the 5-bromo-1H-indole ring with respect to the plane of the 4-methyl-1,4,5,6,7,8-hexa-hydro-quinoline ring [dihedral angles of 78.55 (9) and 89.70 (8)° in molecules A and B, respectively]. The indole ring is planar in(More)
In the title multi-donor Schiff base compound, C(19)H(13)N(3)O·CH(3)OH, the dihedral angle between the mean planes of the phenanthroline and phenol rings is 59.3 (1)°.
