In the title mol-ecule, C19H20N2O2, the imidazole ring makes dihedral angles of 57.29 (5) and 31.54 (5)° with the attached di-meth-oxy-phenyl residue and the phenyl ring, respectively. The dihedral angle between the di-meth-oxy-phenyl and phenyl rings is 61.15 (5)°. In the crystal, pairs of C-H⋯N hydrogen bonds connect the mol-ecules into inversion dimers.

Objective(s): In this study a series of novel colchicine-like β-acetamidoketones was designed and synthesized as potential tubulin inhibitorsMaterials and Methods: The cytotoxicity of the novel synthesized β-acetamidoketones was assessed against two cancerous cell lines including MCF-7 (human breast cancer cells) and A549 (adenocarcinomi...

Ring cleavage occurred when 1,2,4-triazino-1,2,4-triazines (3), (4) and (5) were treated with concentrated hydrochloric acid to yield N-substituted triazines (7) and (8). These confirm the given configuration assigned to the isomeric triazinotriazines. 6-Methyl-2-phenyl-7H-oxazolo [3,2-b][1,2,4]-triazin-7-one (9) underwent ring cleavage on treatment with sodium alkoxide to afford 3-alkoxy-1...

In the title mol-ecule, C(30)H(23)N(5)O(3)S, the 1,2,4-triazole ring is approximately planar (r.m.s. deviation = 0.006 Å), and forms dihedral angles of 66.0 (2), 65.1 (2), 30.1 (2) and 28.1 (2)° with the four phenyl rings. The phenyl ring of the benzyl group directly attached to the triazole ring is almost perpendicular to the nitro-phenyl ring, making a dihedral angle of 84.9 (2)°.

In the title compound, C(8)H(8)N(4)·C(8)H(8)N(4), two tautomers, viz. 3-phenyl-1,2,4-triazol-5-amine and 5-phenyl-1,2,4-triazol-3-amine, are crystallized together in equal amounts. The 3-phenyl-1,2,4-triazol-5-amine mol-ecule is essentially planar; the phenyl ring makes a dihedral angle of 2.3 (2)° with the mean plane of the 1,2,4-triazole ring. In the 5-phenyl-1,2,4-triazol-3-amine tautomer, t...

IN THE TITLE COMPOUND [SYSTEMATIC NAME: 1-(3-phenyl-prop-2-eno-yl)thio-urea], C(10)H(10)N(2)OS, the acetyl-thio-urea fragment and the phenyl ring adopt an E configuration. The roughly planar but-2-enoyl-thio-urea fragment [maximum deviation = 0.053 (3) Å] forms a dihedral of 10.54 (11)° with the phenyl ring. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, mol-ecul...

The mol-ecule of the title compound, C(19)H(15)N(3)O, is approximately planar and displays a trans configuration with respect to the C=N and N=N double bonds. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. The dihedral angles between the hydroxy-phenyl ring and the phenyl and benzene rings are 4.31 (8) and 6.60 (8)°, respectively. The dihedral angle between the phenyl and ...

The title compound, [Ir(C(11)H(8)N)(2)(C(17)H(19)O(2))], has an octa-hedral coordination geometry around the Ir(III) atom, retaining the cis-C,C,trans-N,N chelate disposition of the two 2-phenyl-pyridine ligands. The chelate rings are nearly mutually perpendicular [the inter-planar angles range from 85.48 (17) to 89.17 (19)°]. The two 2-(2-pyrid-yl)phenyl ligands are approximately planar, with ...

The title compound, C(20)H(14)N(6)O(2), contains four rings. The dihedral angle between the pyridine ring and the pyrazole ring is 1.9 (1)°, i.e. almost coplanar, which gives rise to a conjugated structure. The dihedral angle between the nitro-substituted phenyl ring and the pyridine ring is 76.3 (1)° and that between the pyrazole ring and the non-substituted phenyl ring is 40.5 (1)°. In the cr...

A novel acrylate monomer containing 4H-pyran-4-one and 1,2,3-triazole ring, {1-[4-(4-oxo-6-phenyl-4H-pyran-2-yl)benzyl]-1,2,3-triazol-4-yl}methyl acrylate was synthesized by the reaction of 2-{4-[(4-(hydroxymethyl)-1,2,3-triazol-1-yl)methyl]phenyl}-6-phenyl-4H-pyran-4-one with acryloyl chloride in the presence of triethylamine. The structure of the acrylate monomer was established on the basis ...
