The asymmetric unit of the title compound, C(9)H(9)NO(2)·2H(2)O, comprises two independent organic mol-ecules and four water mol-ecules of crystallization. The heterocyclic rings are not planar: in one mol-ecule, the C atom bearing the O atom and the adjacent methyl-ene C atom are displaced by 0.320 (3) and 0.677 (3) Å, respectively, from the other eight atoms of the fused ring system. Equivale...

The asymmetric unit of the title compound, C(15)H(17)NO(2), contains two independent mol-ecules in which the dihedral angles between the pyrrole and benzene rings are 42.43 (9) and 45.70 (9)°. In both mol-ecules, the but-oxy chains are disordered over two sets of sites, with occupancy ratios of 0.701 (7):0.299 (7) and 0.869 (4):0.131 (4). Each mol-ecule forms a dimer with an inversion-related m...

The title compound, C(16)H(15)N(5), crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angles of the pyrimidine ring with the benzene and pyridyl rings are 22.3 (1) and 53.2 (9)°, respectively, in mol-ecule A, and 6.8 (1) and 11.6 (9)° in mol-ecule B. The crystal packing is influenced by the collective action of weak inter-molecular N-H⋯N hydrogen bonds,...

In the title compound, [Ca(C(15)H(9)O(7)S)(H(2)O)(6)](C(15)H(9)O(7)S)·3H(2)O, the Ca centre has a distorted deca-hedral geometry, coordinated by six O atoms from water mol-ecules and one sulfonate O atom. The crystal structure is stabilized by aromatic π-π inter-actions, with centroid-centroid distances of 3.765 (5) and 3.896 (5) Å between the phenyl ring and the benzene ring of the chromene un...

The asymmetric unit of the title compound, C(7)H(6)ClN(3)S, consists of two crystallographically independent mol-ecules (A and B). The dihedral angle between the benzothia-zole ring system and the hydrazine group is 8.71 (6)° in mol-ecule A and 7.16 (6)° in mol-ecule B. The N-N-C-N and N-N-C-S torsion angles involving the hydrazine group are 170.89 (9) and -9.96 (13)°, respectively, in mol-ecul...

There are two mol-ecules in the asymmetric unit of the title imidazole derivative, C(20)H(16)ClFN(2)OS(2). In one mol-ecule, the dithiol-ane ring is disordered over two positions in a 0.849 (9):0.151 (10) ratio. The imidazole ring makes dihedral angles of 79.56 (9) and 18.45 (9)° with the 4-chloro-phenyl and 2-fluoro-phenyl rings, respectively, in one mol-ecule; in the other mol-ecule, the corr...

The title compound, C(20)H(22)O(6), was obtained by the reaction of ethyl 4-hy-droxy-benzoate with 1,2-dichloro-ethane in dimethyl-formamide. The mol-ecule lies around the crystallographic inversion center at (0,0,0), with the asymmetric unit consisting of one half of the mol-ecule. The two ethyl groups are in trans positions. The ethyl, carboxyl, aryl and O-CH(2) groups are coplanar with an r....

Background & Aim: Ocimum basilicum L. is belong to the Lamiaceae family which is cultivated as a culinary, industrial and medicinal plants in some countries from thousands years ago. The seed of this plant is rich in poly un-saturated fatty acids (PUFA) and produced a large amount of mucilage. Experimental: The oil of seed was extracted separately and converted to fatty acids...
