synthesis of 3-(2-(benzyloxy)phenyl)-5-(methylsulfonyl)-4h-1,2,4-triazole as selective cox-2 inhibitor

trans-Bis[1-(2-anilino-2-oxoeth­yl)-3-benzyl-1H-imidazol-2-yl]palladium(II) methanol disolvate

In the title compound, [Pd(C(18)H(16)N(3)O)(2)]·2CH(3)OH, the Pd(II) atom is located on a crystallographic inversion center. It has a square-planar coordination geometry, with the two bidentate ligands coordinated in a trans fashion via the carbene C atom and the amido N atoms. The methanol solvent mol-ecules form O-H⋯O hydrogen bonds with the complex. Additional non-classical inter-molecular C...

1-(2-Methyl-5-nitro-1H-imidazol-1-yl)acetone

In the mol-ecule of the title compound, C7H9N3O3, the nitro and carbonyl groups are tilted with respect to the imidazole ring by 9.16 (6) and 65.47 (7)°, respectively. Neighbouring chains are linked via C-H⋯N and C-H⋯O hydrogen bonds forming two-dimensional slab-like networks lying parallel to (01-1).

2-[2-(5-Bromo­thio­phen-2-yl)-4,5-diphenyl-1H-imidazol-1-yl]-3-phenyl­propan-1-ol

In the title compound, C28H23BrN2OS, the dihedral angles formed by the imidazole ring with the 5-bromo-thio-phenyl and phenyl rings are 76.90 (8), 34.02 (10) and 80.93 (11)°, respectively. The chiral centre maintains the S configuration of the l-phenyl-alaninol starting material. In the crystal, mol-ecules are linked by O-H⋯N hydrogen bonds, forming chains running parallel to the a-axis direction.

2-(1H-Imidazol-1-yl)-4,6-dimethyl­pyrimidine

The asymmetric unit of the title compound, C(9)H(10)N(4), consists of two mol-ecules in which the dihedral angles between the planes of the imidazole and pyrimidine rings are 4.8 (1) and 2.1 (1)°.

1-(2-Methyl-5-nitro-1H-imidazol-1-yl)propan-2-yl acetate

In the title compound, C9H13N3O4, an ester of the anti-infection drug secnidazole, the dihedral angle between the nitro-imidazole mean plane (r.m.s. deviation = 0.028 Å) and the pendant acetate group is 43.17 (11)°. In the crystal, inversion dimers linked by pairs of C-H⋯O inter-actions generate R 2 (2)(10) loops and further C-H⋯O hydrogen bonds link the dimers into [100] chains. Weak aromatic ...
