The title Schiff base compound, C(23)H(23)N(5)O, was synthesized by the reaction of 4-amino-phenazone and 3,5-dimethyl-1-phenyl-pyrazole-4-carbaxaldehyde. The mol-ecule adopts an E configuration about the central C=N double bond. A weak intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. The dihedral angle between the pyrazole rings is 24.72 (10)° and the dihedral angles between t...

The title compound, C(16)H(14)O(3)S, was prepared by the oxidation of 2,5-dimethyl-3-phenyl-sulfanyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. The phenyl ring makes a dihedral angle of 76.98 (9)° with the plane of the benzofuran fragment. The crystal structure is stabilized by π-π inter-actions between furan and benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.775 ...

In the title compound, cis-[PtCl(2)(C(5)H(13)N(3))(C(2)H(6)OS)], the four-coordinate Pt(II) atom is bonded to one N atom of the N,N,N',N'-tetra-methyl-guanidine ligand, one dimethyl sulfoxide S atom and two chloride ligands, forming a cis-square-planar geometry. The bond lengths and angles of the N-Pt-Cl functionality are typical for imine dichloridoplatinum(II) complexes. The H atom of the imi...

In the title compound, C(20)H(26)N(2)O(6)S, the N atom of the dimethyl-amino group is displaced by 0.113 (2) Å from the plane of the naphthalene ring system. The two eth-oxy groups adopt zigzag conformations. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules, forming a three-dimensional network. Both ethyl groups are disordered over two sites with the ratio...

Crystals of the title compound were obtained as a 1:1 dimethyl sulfoxide solvate, C(20)H(16)N(2)O(2)·C(2)H(6)O. The mol-ecular conformation of the organic mol-ecule is similar to that in the previously reported unsolvated structure [Eltayeb et al. (2009 ▶). Acta Cryst. E65, o1374-o1375]. Thus, the dihedral angles formed by the benzimidazole moiety with the two benzene rings are 57.54 (4) and 76...

In the title compound, C(17)H(15)NO(2)S(2), the 3H-benzo[f]chromene ring system is distinctly twisted; the dihedral angle between the pyran ring and its opposite benzene ring is 9.11 (8)°. The N,N-dimethyl-carbamodithio-ate residue lies almost perpendicular to the pyran ring [dihedral angle = 85.15 (7)°]. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into C(10) chains propagatin...

The title compound, [Cu(C(4)H(10)NO)I(C(4)H(11)NO)], was obtained unintentionally as the product of an attempted synthesis of a Cu/Zn mixed-metal complex using zerovalent copper, zinc(II) oxide and ammonium iodide in pure 2-(dimethyl-amino)-ethanol, in air. The mol-ecular complex has no crystallographically imposed symmetry. The coordination geometry around the metal atom is distorted square-py...

In the title compound, C16H8N6O2S2·2C2H6OS, the phenanthroline mol-ecule resides on a twofold axis, and the asymmetric unit also contains a slightly disordered [occupancy ratio for S atom of 0.95 (3):0.047 (3)] mol-ecule of dimethyl sulfoxide. The O atoms of the solvent mol-ecule accept hydrogen bonds from the N-H groups of the five-membered 2,3-di-hydro-1,3,4-oxa-diazole-2-thione ring. This ri...

echinophora platyloba d.c as a medicinal plant is used for preservation of foods and treatment of many diseases in different regions of iran. the present study was undertaken to determine the chemical composition and investigation of the antibacterial effects of essential oil as well as methanol extract from aerial part of echinophora platyloba d.c against s. aureus, l. monocytogenes, s. thyphi...

The reaction of Co(NO(3))(2)·3H(2)O with pyridine-2,6-dicarboxylic acid and 3,5-dimethyl-1H-pyrazole in a 1:1:3 molar ratio affords the title complex, [Co(C(7)H(3)NO(4))(C(5)H(8)N(2))(3)]·H(2)O. The Co(II) atom is coordinated by one pyridine-2,6-dicarboxyl-ate chelating ligand and three 3,5-dimethyl-1H-pyrazole ligands in a distorted octa-hedral geometry. Hydrogen-bonding interactions involving...
