Crystal structure of 1-[2-(4-nitrophenyl)-4,5-diphenyl-1H-imidazol-1-yl]propan-2-ol

2018-10-06 08:07:24 Keywords crystal structure, Multi-substituted Imidazoles, hydrogen bonding., C—Hinter-actions,
Crystal structure of 1-[2-(4-nitrophenyl)-4,5-diphenyl-1H-imidazol-1-yl]propan-2-ol
The title compound, C24H21N3O3, crystallizes with two unique but closely r.m.s. overlay fit = 0.215 A˚) comparable molecules (1 and 2) in the asymmetric unit of the triclinic unit cell. In molecule 1, the dihedral angles between the central imidazlole ring and the benzene-ring substituents are 42.51 (9), 45.41 (9) and 56.92 (8), respectively. Comparable data for molecule 2 are ...

Crystal structure of 1-[2-(4-chlorophenyl)-4,5-diphenyl-1H-imidazol-1-yl]propan-2-ol

2018-10-06 08:11:32 Keywords crystal structure, Multi-substituted Imidazoles, hydrogen bonding., C-H,
Crystal structure of 1-[2-(4-chlorophenyl)-4,5-diphenyl-1H-imidazol-1-yl]propan-2-ol
The title compound, C24H21ClN2O, crystallizes with two unique molecules in the asymmetric unit. In each molecule, the central imidazole ring is substituted at the 2-, 4- and 5-positions by benzene rings. The 2-substituted ring carries a Cl atom at the 4-position. One of the imidazole N atoms in each molecule has a propan-2-ol substituent. In the crystal, a series of ... Read more

Crystal structure of N-[4-amino-5-cyano-6-(methylsulfanyl)pyridin-2-yl]-2-chloroacetamide

2018-09-10 13:09:36 Keywords crystal structure, poly-functional pyridines, acetamide;, hydrogen bonding., 10.1107/S205698901500256X,
Crystal structure of N-[4-amino-5-cyano-6-(methylsulfanyl)pyridin-2-yl]-2-chloroacetamide
The title compound, C9H10N4OS0.5H2O, crystallizes with two independent molecules (A and B) in the asymmetric unit, together with a water molecule of crystallization. The acetamide moiety, which has an extended conformation, is inclined to the pyridine ring by 7.95 (16) in molecule A and by 1.77 (16) in molecule B. In the crystal, the A and B molecules are linked ... Read more
